prince doc.html
--raster-output=doc_%d.png
doc.html and rasterize the output
to the series of files
doc_1.png,
doc_2.png,
doc_3.png etc.
The command-line must contain the name of the input file to process. An input filename consisting of a single hyphen "-" will cause Prince to read from the standard input stream.
The output file name can be specified on the command-line using the
-o command-line option.
An output filename consisting of a single
hyphen "-" will cause Prince to write to the standard output stream.
If the output file name is omitted, the output will be placed in a file with the same name as the input, but with a PDF file extension.
It is necessary to specify the output file when the input is a HTTP or HTTPS URL.
Any of the --long command-line options can either be passed
as a single command-line argument with an equals sign (=), or as two
command-line arguments with space:
--output out.pdf
--output=out.pdf
If the value of a command-line option contains a space or other command characters, the value has to be written between quotation marks.
If rasterization is used, the -o option is optional.
If not specified, a PDF output will not be generated.
The command-line may include the options described below:
-h, --help
--version--credits-v, --verbose
--debug--log=FILE--no-warn-css-unknown--no-warn-css-unsupported--no-warn-css-i FORMAT,

-l,
--input-list=FILE
--baseurl=URL
--remap=URL=DIR
Rather than retrieving documents beginning with
URL get them from the local directory
DIR.
This option can be used multiple times to specify more than one remapping.
It cannot be used with --fileroot.
Note that Prince does not know which file to use when the path maps to a
directory (in other words, an index file).
If http://www.example.com/ is requested, and mapped to
example-com it does not know whether to open
example-com/index.html,
example-com/index.php or any other file
as this is site dependent. In this case Prince will report an error for
that resource.

Rasterization is enabled with the --raster-output option
below.
When this is used the PDF output option (-o) is optional.
--raster-output=TEMPLATE
Enable raster output.
The output files will be named based on the template.
Prince will replace every
'%[WIDTH]d'
with the current page number.
The optional WIDTH value gives the
number of characters the page number should take within the file name.
Smaller page numbers will be padded to the left with either spaces,
or if the width begins with a zero, with zeros.
For example --raster-output=page_%02d.png will cause
Prince to generate
page_01.png,
page_02.png, …,
page_10.png,
page_11.png etc.
Prince also accepts `-' meaning the standard output
stream.
--raster-format=FORMAT
auto (guess based on file extension, the default),
png or jpeg.
If Prince does not recognize the file extension, or
--raster-output is '-',
then it is necessary to provide this option.
--raster-pages=PAGE
all (the default),
first and
NUM (a single page).
--raster-dpi=DPI
--raster-threads=NUM
--raster-background=BACKGROUND
transparent or
white. It can be used when rasterizing to an
image format that supports transparency (PNG, not JPG) and have a
transparent background, so it can be composited with something else
later.
--scanfonts FILES...--capture DIR--replay DIRThe capture/replay system saves a copy of all the information in a job to a specified directory, conveniently allowing it to be replayed later for debugging purposes. See also The capture/replay system.
--controlThe Prince Control Protocol is a synchronous bidirectional protocol that consists of a sequence of "chunks" sent via the standard input and output streams. For more details, please check the detailed documentation in the separate Prince Control Protocol chapter.
--structured-log=LEVELThe Structured Log option is a formatting option for Prince's output to stderr. For more details, please check the detailed documentation in the separate Structured Log chapter.

| Inherited | no |
columns: column-count | column-width| Initial value | 1 |
|---|---|
| Applies to | non-replaced block-level elements (except table elements), table cells, and inline-block elements |

The columns property is a shorthand for
setting the following CSS properties:
content: normal | flow( name, page-policy? ) | [ "string" | url( filename ) | counter( name, counter-style?, page-policy? ) | counters( name, "separator", counter-style?, page-policy? ) | target-counter( url, counter, counter-style? ) | target-counters( url, counter, "separator", counter-style? ) | target-content( url ) | leader( "..." | dotted | solid | space ) | string( ident, page-policy? ) | content( ) | prince-base-url( ) | prince-script( ident, content? ) | prince-glyph-index( number ) | prince-fallback( url ) [ , content+ ]? | element( name ) ]+| Initial value | normal |
|---|---|
| Applies to | all elements, tree-abiding pseudo-elements, and page regions |

Filters section.
flex: none | [ flex-grow flex-shrink? || flex-basis ]| Initial value | 1 0 auto |
|---|---|
| Applies to | flex items |
| Inherited | no |
The flex property is a shorthand for
setting the following CSS properties:

|---|---|
| Applies to | flex containers |
| Inherited | no |

float:
none | left | right | inside | outside
| footnote | inline-footnote
| prince-column-footnote
| prince-column-inline-footnote
| prince-snap
| [ [ top | bottom | column-top | column-bottom
| column-top-corner | column-bottom-corner ]
&& [ next | unless-fit ]? ]| Initial value | none |
|---|---|
| Applies to | all elements |
| Inherited | no |
Traditionally, floats move in the inline direction, left or right. Prince extends this behavior with page floats that move in the block direction, specifying that an element should be floated to the top or to the bottom, or to the nearest edge of the column.
The values top or bottom float the element to, respectively,
the top or the bottom of the page.
The values column-top and column-bottom float the element
to the top or bottom of the column it appears in.
The values column-top-corner and column-bottom-corner
float the element to the top or bottom of the last column, rather than its natural
column.
The value prince-snap floats the element to the nearest "end", i.e.
to the top or bottom of the page, or of the column in the case of a multi-column
layout.
The values inside and outside float the element respectively
to the inside or outside of a spread: inside moves the element to
the right when used on a left-facing page, and to the left on a right-facing page;
outside moves the element to the left when used on a left-facing
page, and to the right on a right-facing page. When these values are used in
a multi-column layout, the element is floated to the inside or outside of the
column it appears in its natural flow.
The value footnote transforms the element into a footnote - the footnote
marker is placed outside of the block of the footnote. The value inline-footnote
transforms the element into a footnote and places the footnote marker inside of
the block of the footnote.
The values prince-column-footnote and prince-column-inline-footnote
behave in an analogous way, but move the footnote not to the bottom of the page,
but to the bottom of its column instead.
The additional modifier next defers the float to the next column in
a multi-column layout, otherwise it defers the float to the next page.
The modifier unless-fit expresses a conditional: the element is only
floated if it would otherwise cause a page or column break.
flow: normal | static( name, [ start | current ]? )| Initial value | normal |
|---|---|
| Applies to | all elements |
| Inherited | no |
This property is used to remove elements from the normal flow of the
document, to be placed in a page region with content: flow(),
in order to create running page headers and footers.
The optional start argument (default is current)
makes the fetched content available, as if it were fetched from the start
of the document.
See the documentation for Taking elements from the document for more details.
The property prince-flow can be used as an alias.
font: font-style? font-variant? font-weight? font-size [ / line-height ]? font-family| Initial value | 12pt serif |
|---|---|
| Applies to | all elements |
| Inherited | yes |
font: bold 14pt/16pt Georgia, "Times New Roman", serif
The font property is a shorthand for
setting the following CSS properties:
font-family: [ serif | sans-serif | monospace | name | "name" ]# prince-no-fallback?| Initial value | serif |
|---|---|
| Applies to | all elements |
| Inherited | yes |
font-family: Georgia, "Times New Roman", serif
font-family: MyFont, prince-no-fallback
The special keyword prince-no-fallback triggers a warning if
any glyphs are not found in the specified font, whereas normally Prince
would silently fallback to serif.
When used as a descriptor for the
@font-face at-rule,
font-family defines the font family name that will be used in
all CSS font family name matching. It is required for the @font-face
rule to be valid.
font-size: length | percent | smaller | larger | xx-small | x-small | small | medium | large | x-large | xx-large| Initial value | 12pt |
|---|---|
| Applies to | all elements |
| Inherited | yes |
font-stretch: ultra-condensed | extra-condensed | condensed | semi-condensed | normal | semi-expanded | expanded | extra-expanded | ultra-expanded | wider | narrower| Initial value | normal |
|---|---|
| Applies to | all elements |
| Inherited | yes |

|---|---|
| Applies to | all elements |
| Inherited | yes |
<span style="font-family: SpecialFont; font-variant: prince-opentype(aalt(2))">&</span>
font-variant: prince-opentype(onum, ccmp, liga)
The prince-opentype() function takes a comma-separated list of
OpenType features. Microsoft has a list of the OpenType feature names
here.
Some OpenType features like aalt (access all alternates) can be
used to select one of many optional glyphs, eg. a font might provide three different
ampersand glyphs and allow the author to choose which one. An optional integer
parameter is how you do this, however it requires intimate details of exactly
which font is being used and what glyphs it provides.
The feature can be written either in function form (feature(N))
or in concatenated form (featureN).
The keyword prince-no-kerning disables the kern
OpenType feature, which defines font kerning.
font-weight: normal | bold | bolder | lighter | 100 | 200 | 300 | 400 | 500 | 600 | 700 | 800 | 900| Initial value | normal |
|---|---|
| Applies to | all elements |
| Inherited | yes |
footnote-display: block | inline | compact| Initial value | block |
|---|---|
| Applies to | footnote elements |
| Inherited | no |
This property provides a convenient way of determining whether footnotes should be displayed as a block element or an inline element.
The value compact leaves it up to Prince to determine whether
to display the footnote as a block or inline element: if two or more footnotes
fit on one line, they will be treated as inline elements to take up less space.
footnote-style-position: outside | inside| Initial value | outside |
|---|---|
| Applies to | footnote elements |
| Inherited | yes |
For information about the use of the footnote-style-position
property see the documentation for Footnotes.

This property defines if hyphenation is allowed to create more wrapping points in a line of text.
hyphenate-patterns: none | url( patterns-url )| Initial value | none |
|---|---|
| Applies to | all elements |
| Inherited | yes |
This property is used to point to a hyphenation dictionary. Normally this is selected automatically, based on the current language.
The property prince-hyphenate-patterns can be used as an alias.
hyphenate-after: integer| Initial value | 1 |
|---|---|
| Applies to | all elements |
| Inherited | yes |
This property specifies the minimum number of letters in a word that may be moved to the next line when the word is hyphenated.

hyphenate-character: auto | "string"| Initial value | auto |
|---|---|
| Applies to | all elements |
| Inherited | yes |
This property specifies the character that is shown at the end of a line when the word is hyphenated.
The property prince-hyphenate-character can be used as an alias.
hyphenate-lines: no-limit | integer| Initial value | no-limit |
|---|---|
| Applies to | all elements |
| Inherited | yes |
This property specifies the maximum number of consecutive lines that may end with a hyphenated word.
The property prince-hyphenate-limit-lines can be used as an alias.
image-resolution: dpi | normal | auto [ , normal | dpi ]?| Initial value | normal |
|---|---|
| Applies to | image elements |
| Inherited | yes |
This property determines the resolution of an image. The value normal
means 96dpi, or else the current CSS DPI setting. A custom DPI value can also
be specified. The value auto means to check the original resolution
of the image. One can specify a second value, as for example auto, normal
or auto, 300dpi in order to check the original resolution of the
image first, and to fall back on the second value if the image doesn't contain
resolution information.
The property prince-image-resolution can be used as an alias.
image-orientation: none | from-image| Initial value | none |
|---|---|
| Applies to | all elements |
| Inherited | yes |
This property adds support for the orientation field in the EXIF data of JPEG and TIFF images.
The property applies only to content images (e.g. replaced elements and
generated content), not decorative images (such as background-image).
justify-content: flex-start | flex-end | center | space-between | space-around| Initial value | flex-start |
|---|---|
| Applies to | flex containers |
| Inherited | no |
letter-spacing: normal | length| Initial value | normal |
|---|---|
| Applies to | all elements |
| Inherited | yes |
line-stacking-strategy: inline-line-height | block-line-height | max-height | grid-height| Initial value | inline-line-height |
|---|---|
| Applies to | block-level elements |
| Inherited | yes |
This property allows to choose whether individual lines should have their height determined based on their content, or whether all lines in a paragraph should have the same height, or a compromise where their heights are determined by their content and then rounded up to a multiple of the paragraph line height.
The behavior define by inline-line-height is the default.
The value block-line-height uses the line-height of the block
element and ignores the actual height of the content on those lines, so lines
will always have the same spacing regardless of whether they contain spans
with larger font size of superscripts/subscripts.
The value grid-height is like inline-line-height
but each line gets rounded up to an integer multiple of the block line-height.
Finally, the max-height value works like inline-line-height,
but it ignores the line-height property value
for inline elements.
line-height: normal | none | number | length | percent| Initial value | normal |
|---|---|
| Applies to | all elements |
| Inherited | yes |
link: none | url( target-url ) | attr( target-attr )| Initial value | none |
|---|---|

|---|---|
| Applies to | all elements, except elements with table display types other than table-caption, table and inline-table |
| Inherited | no |
The margin property is a shorthand for
setting the following CSS properties:
margin-inside: auto | length | percent| Initial value | auto |
|---|---|
| Applies to | all elements, except elements with table display types other than table-caption, table and inline-table |
| Inherited | no |
The margin-inside property overrides the value of the
margin-right property if the element is on a left-facing
page and overrides the value of the margin-left property
if the element is on a right-facing page. The result is a horizontal
margin on the side of the element that is on the "inside" of the
two-page spread.
margin-outside: auto | length | percent| Initial value | auto |
|---|---|
| Applies to | all elements, except elements with table display types other than table-caption, table and inline-table |
| Inherited | no |

marks: none | [ crop || cross ]| Initial value | none |
|---|---|
| Applies to | @page at-rule |
| Inherited |
@page { marks: crop }@page { marks: crop cross }
This CSS at-rule descriptor, used with the
@page at-rule, adds
crop and/or cross marks to the page.
Specifying crop and/or cross for
the marks property will result in 6pt of bleed area being
added to all four sides of the page and additional trim area to
contain the crop marks.
mask: url( mask )| Initial value | none |
|---|---|
| Applies to | all elements |
| Inherited | no |

| Inherited | no |
orphans: integer| Initial value | 1 |
|---|---|
| Applies to | block container elements |

overflow: visible | hidden| Initial value | visible |
|---|---|
| Applies to | non-replaced block-level elements and non-replaced inline-block elements |
| Inherited | no |
This property determines the visibility of content that overflows outside the boundaries of an element.
overflow-wrap: normal | break-word| Initial value | normal |
|---|---|
| Applies to | all elements |
| Inherited | yes |
part { overflow-wrap: break-word; }
supplier, item { overflow-wrap: normal; }
<part><supplier>xyz</supplier><item>12345</item></part>This property controls wrapping behavior of last resort:
whether it is better for a word to overflow its container,
or to be broken at an arbitrary point
(subject to white-space, and not splitting within a grapheme cluster),
without adding a hyphen.
The value normal allows text containing no other wrap
opportunities to overflow.
This feature is most commonly used for non-words such as URIs, part codes,
or cryptographic hashes.
For such purposes, overflow-wrap:break-word can be
compared with word-break:break-all:
the latter is more willing to break the word (preferring to break
than to leave an under-full line or advance past a CSS2-style float),
but only breaks between alpha-numeric grapheme clusters rather than
between any pair of grapheme clusters.
The element whose overflow-wrap property controls
whether such a wrap opportunity exists at a given boundary
is the closest ancestor that “strictly contains” the boundary,
i.e. that contains text from both sides of the boundary.
Thus, components of a wrappable string can be kept on one line
by styling each component with overflow-wrap:normal
even if two components are directly adjacent to each other, as
seen in the above example.
padding: [ length | percent ] {1..4}| Initial value | 0 |
|---|---|
| Applies to | all elements, except table-row-group, table-header-group, table-footer-group, table-row, table-column-group and table-column |
| Inherited | no |
The padding property is a shorthand for
setting the following CSS properties:

position: static | relative | absolute | fixed | running( name )| Initial value | static |
|---|---|
| Applies to | all elements |
| Inherited | no |
The running() function removes the element from the normal document
flow and makes it available to be placed in a page region with the
element() function of the content
property. See also Taking elements from the document.
prince-background-image-resolution: dpi | normal | auto [ , normal | dpi ]?| Initial value | normal |
|---|---|
| Applies to | background image elements |
| Inherited | yes |
This property determines the resolution of a background image. The value normal
means 96dpi, or else the current CSS DPI setting. A custom DPI value can also
be specified. The value auto means to check the original resolution
of the image. One can specify a second value, as for example auto, normal
or auto, 300dpi in order to check the original resolution of the
image first, and to fall back on the second value if the image doesn't contain
resolution information.
The property background-image-resolution can be used as an alias.
prince-bleed: auto | [ length ] {1..4}| Initial value | auto |
|---|---|
| Applies to | @page at-rule |

@page { prince-bleed: 10mm }This CSS at-rule descriptor can be used to specify the size of the bleed area of the page when crop marks are enabled.
The property bleed can be used as an alias.
prince-bookmark-label: none | content| Initial value | content() |
|---|---|
| Applies to | all elements |
| Inherited | no |
This property is used to determine the text content of the PDF bookmark generated by the current element.
Several ways of creating content are here defined by means of functions - the detailed explanation can be found in the Generated Content Functions section.
Even though the initial value for this property is
content(), no PDF bookmark will be generated by default
as the initial value for the prince-bookmark-level
property is none.
See the documentation for PDF Bookmarks for more details.
The property bookmark-label can be used as an alias.
prince-bookmark-level: none | integer| Initial value | none |
|---|---|
| Applies to | all elements |
| Inherited | no |
This property is used to determine the numeric level in the bookmark hierarchy of the PDF bookmark generated by the current element. See the documentation for PDF Bookmarks for more details.

prince-bookmark-state: open | closed| Initial value | open |
|---|---|
| Applies to | all elements |
| Inherited | no |
This property is used to determine whether the bookmark tree item is open or closed when the PDF is first viewed. In this way you can close each chapter and hide the subsections for documents that are very long, or you can choose to have a deep bookmark tree.
The property bookmark-state can be used as an alias.
prince-bookmark-target: self | url( target-url ) | attr( target-attr )| Initial value | self |
|---|---|

| Inherited |
@prince-pdf {
prince-pdf-output-intent: url("AdobeRGB1998.icc");
prince-fallback-cmyk-profile: url("ISOcoated_v2_eci.icc");
}
This property is used inside a
@prince-pdf
at-rule to determine a fallback CMYK profile to be used for uncalibrated
(untagged) CMYK colors or images, if it is not possible to use the output
intent ICC profile (see prince-pdf-output-intent).
CMYK colors are treated as uncalibrated in either of the following three cases: conversion of an untagged CMYK image to another color space, conversion of a device dependent CMYK color, or when a PDF Profile requires that only device independent color is present, in which case both untagged CMYK images and device dependent CMYK colors are treated as uncalibrated CMYK colors.
prince-filter-resolution: dpi| Initial value | 96dpi |
|---|---|
| Applies to | all elements, @prince-pdf at-rule |
| Inherited |
This property is used to specify the resolution used when
rasterizing to images for applying CSS and SVG filters. It can be
used for individual elements, or inside a

at-rule. In this latter case, it affects all filters in the document.
prince-flow: normal | static( name, [ start | current ]? )| Initial value | normal |
|---|---|
| Applies to | all elements |
| Inherited | no |
This property is used to remove elements from the normal flow of the
document, to be placed in a page region with content: flow(),
in order to create running page headers and footers.
The optional start argument (default is current)
makes the fetched content available, as if it were fetched from the start

The property flow can be used as an alias.
prince-footnote-policy: auto | keep-with-line | keep-with-block| Initial value | auto |
|---|---|
| Applies to | footnote elements |
| Inherited | yes |
This property determines whether a footnote should always be displayed on the
same page as its footnote call is located on, or whether it may slip to the next
page. The value keep-with-line instructs Prince to keep the footnote
on the same page as the line with the footnote call, while keep-with-block
tells Prince to keep it together with the whole paragraph with the footnote call.
The property must be applied to the paragraph in which the footnote occurs, not to the footnote element itself.
prince-forced-breaks: short | full| Initial value | short |
|---|---|
| Applies to | all elements |
| Inherited | yes |
This property controls whether a line ended by a “preserved newline”
(such as introduced by <br>)
should preferably appear to be a normal full line (as if ended only by normal line wrapping),
or whether being shorter than a normal full line is actually preferable,
for example to mark a deliberate break.
The difference is particularly marked in justified text,
where lines ended by prince-forced-breaks:full are subject to
justification like most other lines.
(Limitation: At the time of writing, this property only affects justified text.)
This property only applies to Prince for Books.
prince-hyphenate-patterns: none | url( patterns-url )| Initial value | none |
|---|---|
| Applies to | all elements |
| Inherited | yes |
This property is used to point to a hyphenation dictionary. Normally this is selected automatically, based on the current language.
The property hyphenate-patterns can be used as an alias.
prince-hyphenate-after: integer| Initial value | 1 |
|---|---|
| Applies to | all elements |
| Inherited | yes |
This property specifies the minimum number of letters in a word that may be moved to the next line when the word is hyphenated.
The property hyphenate-after can be used as an alias.
prince-hyphenate-before: integer| Initial value | 1 |
|---|---|
| Applies to | all elements |
| Inherited | yes |
This property specifies the minimum number of letters in a word that may be left at the end of a line when the word is hyphenated.
The property hyphenate-before can be used as an alias.
prince-hyphenate-character: auto | "string"| Initial value | auto |
|---|---|
| Applies to | all elements |
| Inherited | yes |
This property specifies the character that is shown at the end of a line when the word is hyphenated.
The property hyphenate-character can be used as an alias.
prince-hyphenate-limit-lines: no-limit | integer| Initial value | no-limit |
|---|---|
| Applies to | all elements |
| Inherited | yes |
This property specifies the maximum number of consecutive lines that may end with a hyphenated word.
The property hyphenate-lines can be used as an alias.
prince-hyphenate-lines: no-limit | integer| Initial value | no-limit |
|---|---|
| Applies to | all elements |
| Inherited | yes |
This property specifies the maximum number of consecutive lines that may end with a hyphenated word.
The property prince-hyphenate-limit-lines can be used as an alias.
prince-image-magic: none | [ snap-to-integer-coords || ignore-icc-profile || [ jpeg-verbatim | recompress-jpeg( percent ) ] || [ convert-to-jpeg | convert-to-jpeg( percent ) ] ]| Initial value | none |
|---|---|
| Applies to | image elements |
| Inherited | yes |
This property performs various image-related, Prince-specific tasks that do not fit into other existing CSS properties. It applies magic to images!
The snap-to-integer-coords value can be used to avoid blurring of
images in some PDF viewers.
The ignore-icc-profile value causes Prince to ignore any ICC color
profile embedded in the image.
The jpeg-verbatim value inhibits the normal stripping that Prince
performs, where unnecessary metadata is removed from JPEG images when they are
embedded in the PDF file.
When recompress-jpeg(quality%) is specified for this property, Prince
will recompress JPEG images to the specified percentage to save space when
embedding them in the PDF output.
The convert-to-jpeg keyword or the convert-to-jpeg(quality%)
function convert non-JPEG images to JPEG, so that they take less space (but may look blurry).
Several of the values can be combined, to perform more than one magic on images.
prince-image-resolution: dpi | normal | auto [ , normal | dpi ]?| Initial value | normal |
|---|---|
| Applies to | image elements |
| Inherited | yes |
This property determines the resolution of an image. The value normal
means 96dpi, or else the current CSS DPI setting. A custom DPI value can also
be specified. The value auto means to check the original resolution
of the image. One can specify a second value, as for example auto, normal
or auto, 300dpi in order to check the original resolution of the
image first, and to fall back on the second value if the image doesn't contain
resolution information.
The property image-resolution can be used as an alias.
prince-linebreak-magic: none | auto| Initial value | auto |
|---|---|
| Applies to | all elements |
| Inherited | yes |
This property enables line-breaking in certain situations even in the absence of whitespace. For example, after slashes in long URLs. It can be disabled for situations in which more precise control over line-breaking behavior is preferred.
prince-line-break-choices: body | heading | title | body-lookahead | heading-lookahead | title-lookahead | fast| Initial value | body |
|---|---|
| Applies to | all elements |
| Inherited | yes |
This property is used for fine tuning the line breaking approach.
The keyword title is intended for title pages of books or
chapters, where phrasing considerations are of prime consideration even
at the cost of extremely unbalanced lines.
The keyword heading, on the other hand, is closer to
body, differing mainly in that it's less likely to hyphenate,
and is more willing to make the first line(s) a little shorter if doing so
avoids a short last line.
The *-lookahead keywords enable paragraph-at-a-time line-breaking
for the paragraph in a non-justified paragraph: choosing where to end the line
not just based on what seems best for the current line, but also considering
the effect on future lines.
The keyword fast can be used for quick web-browers–style line
breaking, useful for testing the effect of styling changes that don't depend
on good line breaking.
For more details, please see Line breaking.
This property only applies to Prince for Books.
The property prince-text-wrap can be used as an alias.
prince-mark-length: length| Initial value | 24pt |
|---|---|
| Applies to | @page at-rule |
| Inherited |
@page { prince-mark-length: 2cm }This CSS at-rule descriptor can be used to specify the length of crop marks, beginning after the offset from the page area and extending towards the edge of the paper.
prince-mark-offset: auto | [ length ] {1..4}| Initial value | auto |
|---|---|
| Applies to | @page at-rule |
| Inherited |
@page { prince-mark-offset: 6pt }This CSS at-rule descriptor can be used to specify the offset between crop and cross marks and the page area.
prince-mark-width: width| Initial value | 0.1pt |
|---|---|
| Applies to | @page at-rule |
| Inherited |
@page { prince-mark-width: 1pt }This CSS at-rule descriptor can be used to specify the line width of the crop and cross marks.
prince-n-lines: auto | integer? [ longer | shorter ] | change | integer| Initial value | auto |
|---|---|
| Applies to | "paragraphs": block container boxes that establish inline formatting contexts |
| Inherited | no |
This property is for use in the pagination phase of typesetting, for ensuring that page ends are even while avoiding widows and other awkward breaks.
Values other than the initial value of auto request that the
paragraph occupy the given number of lines; where values other than a simple
integer are relative to the number of lines that the paragraph would have
occupied if this property still had its initial value (auto).
The value change means to make the paragraph either a line
longer or shorter, whichever will be deemed to look better. This value is
provided for the common case that a page break opportunity exists both at a
line earlier and at a line later than where the page end would naturally
fall, as would typically be the case if the only relevant restriction arises
from widows:2 or orphans:2 or a minor heading that
occupies two body lines worth of height. Thus, this tends to be the most
commonly used value for this property, other than leaving at its initial
value.
A simple integer value is the least convenient value to use (since choosing the desired number requires counting the existing number of lines, and since this property is most commonly used on long paragraphs). Its value lies in the fact that the result is not subject to variation in "the number of lines that the paragraph would otherwise have had", as can occur if this paragraph spans a page end, and a subsequent styling change causes some earlier content to change in size, affecting what is the last line before the break, and if this in turn affects line-breaking decisions made to avoid having a hyphenation at the end of a page.
This property only applies to Prince for Books.
prince-page-fill: prefer-balance | prefer-fill| Initial value | prefer-fill |
|---|---|
| Applies to | @page at-rule |
| Inherited | no |
This property determines whether Prince should balance text layout on page spreads.
This property only applies to Prince for Books.
prince-page-group: start | auto| Initial value | auto |
|---|---|
| Applies to | all elements |
| Inherited | no |
This property determines whether the first page of this element matches the :first page class selector.
The property page-group can be used as an alias.
prince-pdf-color-conversion: none | full| Initial value | none |
|---|---|
| Applies to | @prince-pdf at-rule |
| Inherited | no |
This property may be used inside the
@prince-pdf
at-rule to convert the colors of the PDF to the output intent color space.
It functions like the --convert-colors command-line option.
prince-pdf-color-options: auto | use-true-black | use-rich-black| Initial value | auto |
|---|---|
| Applies to | @prince-pdf at-rule |
| Inherited | no |
@prince-pdf {
prince-pdf-color-options: use-rich-black;
}This property may be used to control the encoding of RGB blacks and grays:
when use-true-black is used, they are encoded in the /DeviceGray colorspace
in the PDF, instead of /DeviceRGB, whereas use-rich-black disables this behavior
and keeps all the colors in RGB. Currently, auto is equivalent to use-true-black.
prince-pdf-destination: none | "name" | attr( attr )| Initial value | none |
|---|---|
| Applies to | all elements |
| Inherited | no |
This property may be used to create "named destinations" (nameddest)
in generated PDF files which can be linked to from other documents.
prince-pdf-duplex: auto | simplex | duplex-flip-short-edge | duplex-flip-long-edge| Initial value | auto |

at-rule to set the Duplex property in the
PDFViewerPreferences dictionary.
prince-pdf-link-type: auto | web | file| Initial value | auto |
|---|---|
| Applies to | @prince-pdf at-rule |
| Inherited | no |
This property controls whether relative links should be embedded in the PDF as web (URL) links or file links. By default they will be resolved against the base URL of the input document.
prince-pdf-open-action: none | [ print | command( ident ) | zoom( fit-page | fit-width | fit-height | percent ) ]+| Initial value | none |
|---|---|
| Applies to | @prince-pdf at-rule |
| Inherited |
@prince-pdf {
prince-pdf-open-action: zoom(fit-page) print;
}This property specifies a space-separated list of actions to perform when the PDF file is opened, like eg. popping up the print dialog box automatically, or setting the default zoom level for PDF documents. Any arbitrary identifier can be specified, although these may be PDF viewer specific; Acrobat can take just about any menu item.
prince-pdf-output-intent: auto | url( filename )| Initial value | auto |
|---|---|
| Applies to | @prince-pdf at-rule |
| Inherited |
@prince-pdf {
prince-pdf-output-intent: url("ISOcoated_v2_eci.icc")
}
This property is used inside a @prince-pdf
at-rule to select the intended output color space of the generated PDF file.
prince-pdf-page-colorspace: auto | none | rgb | cmyk | gray| Initial value | auto |
|---|---|
| Applies to | @page at-rule |
| Inherited | no |
@page {
prince-pdf-page-colorspace: cmyk;
}
This CSS at-rule descriptor can control the colorspace of pages in the PDF file, which affects
blending of transparent content. The keyword auto is currently equivalent
of rgb.
prince-pdf-page-label: auto | content| Initial value | auto |
|---|---|
| Applies to | @page at-rule |
| Inherited |
@page {
prince-pdf-page-label: counter(page, lower-roman)
}This CSS at-rule descriptor can be used to set the page label that will be displayed in the PDF viewer.
Several ways of creating content are here defined by means of functions - the detailed explanation can be found in the Generated Content Functions section.
prince-pdf-page-layout: auto | single-page | two-page | two-page-left | two-page-right | one-column | two-column | two-column-left | two-column-right| Initial value | auto |
|---|---|
| Applies to | @prince-pdf at-rule |
| Inherited |
@prince-pdf {
prince-pdf-page-layout: two-column
}This property can be used to set the default page layout for the PDF file when it is opened. For example, whether the PDF pages should be displayed in one or two columns.
prince-pdf-page-mode: auto | show-attachments | show-bookmarks | fullscreen| Initial value | auto |
|---|---|
| Applies to | @prince-pdf at-rule |
| Inherited |
@prince-pdf {
prince-pdf-page-mode: show-bookmarks
}This property can be used to set the default page mode for the PDF file when it is opened. For example, whether the bookmarks panel should be displayed, and whether the viewer should be fullscreen.
prince-pdf-paper-tray: auto | pick-tray-by-pdf-size| Initial value | auto |
|---|---|
| Applies to | @prince-pdf at-rule |
| Inherited |
@prince-pdf {
prince-pdf-paper-tray: pick-tray-by-pdf-size
}This property controls the PickTrayByPDFSize flag in generated PDF files, which specifies whether the PDF page size is used to select the input paper tray. (See the checkbox in the Acrobat print dialog).

|---|---|
| Applies to | @prince-pdf at-rule |
| Inherited |
@prince-pdf {
prince-pdf-profile: "PDF/X-3:2003"
}PDF Profiles are used to optimize the PDF file for its specific use - for more details and the supported PDF profiles, see PDF Versions and Profiles.
prince-pdf-script: "JavaScript"| Initial value | "" |
|---|---|
| Applies to | @prince-pdf at-rule |
| Inherited |
@prince-pdf {
prince-pdf-script: "this.print();"
}This property can be used to include JavaScript code that will be executed when the PDF file is opened. A common use case is to activate the "Print" dialog automatically.

prince-pdf-xmp: url( filename )| Initial value | "" |
|---|---|
| Applies to | |
| Inherited |
@prince-pdf {
prince-pdf-xmp: url("xmp-file.xmp");
}
This property can be used inside a @prince-pdf
rule to add XMP metadata to a PDF file. Currently it takes an XMP
file as input and includes data from the <x:xmpmeta> element
and its contents (the xpacket processing instructions are ignored, as
Prince generates those itself when it produces the PDF file).
This property requires either a URL pointing to an XMP
file, or an encoded data: URL.
prince-rotate-body: portrait | landscape | angle| Initial value | 0deg |
|---|---|
| Applies to | @page at-rule |
| Inherited |
@page {
prince-rotate-body: landscape
}This CSS at-rule descriptor can be used to rotate the page body, eg. to fit landscape content on a portrait page, while leaving the headers and footers where they are.
Please see the size property for determining
the default orientation of the page.
prince-shrink-to-fit: none | auto| Initial value | none |
|---|---|
| Applies to | @page at-rule |
| Inherited |
@page {
prince-shrink-to-fit: auto
}
Specifying a value of auto will result in wide web pages being scaled
down in size to fit the paper width.
prince-table-column-span: number | attr( colspan )| Initial value | 1 |
|---|---|
| Applies to | table cells |
| Inherited | no |
This property applies to table cells and determines the number of table columns spanned by the table cell. See the Tables documentation for more details.

The property table-row-span can be used as an alias.
prince-text-justify: auto | prince-cjk| Initial value | auto |
|---|---|
| Applies to | all elements |
| Inherited | yes |
This property defines how to treat justified text. The value prince-cjk
allows space to be inserted between CJK characters when justifying even if there
aren't any space characters.
prince-text-replace: none | [ "search" "replace" ]+| Initial value | none |
|---|---|
| Applies to | all elements |
| Inherited | no |
body {
prince-text-replace: "s" "\017F"
"\017F\20" "s\20";
}This property can be used to replace a character string with another one. In the above example, all occurrences of "s" are replaced with the "long s", except if in the end of a word, where the replacement is reversed.
prince-text-wrap: body | heading | title | body-lookahead | heading-lookahead | title-lookahead | fast| Initial value | body |
|---|---|
| Applies to | all elements |
| Inherited | yes |
This property is used for fine tuning the line breaking approach.
The keyword title is intended for title pages of books or
chapters, where phrasing considerations are of prime consideration even
at the cost of extremely unbalanced lines.
The keyword heading, on the other hand, is closer to
body, differing mainly in that it's less likely to hyphenate,
and is more willing to make the first line(s) a little shorter if doing so
avoids a short last line.
The *-lookahead keywords enable paragraph-at-a-time line-breaking
for the paragraph in a non-justified paragraph: choosing where to end the line
not just based on what seems best for the current line, but also considering
the effect on future lines.
The keyword fast can be used for quick web-browers–style line
breaking, useful for testing the effect of styling changes that don't depend
on good line breaking.
For more details, please see Line breaking.
This property only applies to Prince for Books.
The property prince-line-break-choices can be used as an alias.
prince-tooltip: transparent | none | normal | content| Initial value | transparent |
|---|---|
| Applies to | all elements |
| Inherited | no |
*[title] {
prince-tooltip: attr(title)
}
The prince-tooltip property can be used to create a tooltip when
hovering an element in the PDF file. The keyword none actually
"suppresses" tooltips, which means that it will not show any tooltip for
objects underneath the selected element, that might have a tooltip. An empty
string, or some content that evaluates to an empty string, is treated
equivalent to none, rather than showing an empty tooltip.
Several ways of creating content are here defined by means of functions - the detailed explanation can be found in the Generated Content Functions section.
Tooltips are not a standard PDF feature, and they may only work in Adobe Reader and Adobe Acrobat and may not be visible in other PDF viewers, such as web browsers.
prince-trim: auto | [ length ] {1..4}| Initial value | auto |
|---|---|
| Applies to | @page at-rule |
| Inherited |
@page {
prince-trim: 60mm
}This CSS at-rule descriptor can be used to specify the size of the trim area of the page when crop marks are enabled.
prince-wrap-inside: auto | phrase | avoid| Initial value | auto |
|---|---|
| Applies to | all elements |
| Inherited | no |
prince-wrap-inside:phrase is for marking up a phrase
that one would weakly prefer to keep on a single line.
It adds to Prince's perceived cost of breaking within that phrase, but only a small cost, comparable to the cost of hyphenating a compound adjective such as ‘midyear’.
prince-wrap-inside:avoid is a stronger directive:
it avoids breaking the text to which the property is applied even if
it causes the affected text to be unusually tight, or the previous
line to be unusually loose;
but not if either line would become truly exceptionally tightly
or loosely spaced.
(Limitation: At the time of writing, prince-wrap-inside only affects justified text.)
This property only applies to Prince for Books.
size: paper-size | length length [ landscape | portrait ]?| Initial value | Letter |
|---|---|
| Applies to | @page at-rule |
| Inherited |
@page { size: A4 }@page { size: A4 landscape }@page { size: Letter }@page { size: 10cm 5cm }
This CSS at-rule descriptor, used with the
@page at-rule, defines
the size and orientation of the page. Please see also the
prince-rotate-body property to control the
orientation of selected pages.
src: [ url( filename ) [ format( [ "format" ]+ ) ]? | local( name ) | prince-lookup( name ) ]+| Initial value | n/a |
|---|---|
| Applies to | @font-face at-rule |
| Inherited |
@font-face {
font-family: MyFontA;
src: local("Local_Font_A");
}
@font-face {
font-family: MyFontB;
src: prince-lookup("MyFontA");
}
This CSS at-rule descriptor, used with the
@font-face at-rule,
specifies the resource containing font data. It is required for the @font-face
rule to be valid.
Prince supports WOFF (Web Open Font Format), TrueType and OpenType font formats,
expressed respectively by the woff, truetype and
opentype format hints with the optional format()
function.
The local() function searches for locally installed system
fonts, while prince-lookup() will also find fonts defined by
other @font-face rules.
stop-opacity: number| Initial value | 1 |
|---|---|
| Applies to | SVG elements |
| Inherited | yes |
The stop-opacity property only applies to SVG elements.
string-set: none | [ ident content ]+| Initial value | none |
|---|---|
| Applies to | all elements |
| Inherited | no |
This property can be used to create a named string, which may then be referenced
from the content property to create generated
content. Typically this is achieved with the content() function,
which retrieves the text of the selected element.
But any other means of generating content, as described in the Generated Content Functions section, are available. See also Page regions for more details.
stroke: none | color | url( paint-server )| Initial value | none |
|---|---|
| Applies to | SVG elements |

tab-size: number | length| Initial value | 8 |
|---|---|
| Applies to | block containers |
| Inherited | yes |
This property determines the tab-size for preserved tab characters (U+0009). An integer defines number of spaces in a tab, a length represents the width of a tab.
text-align: left | right | inside | outside | center | justify| Initial value | left |
|---|---|
| Applies to | block containers |
| Inherited | yes |
text-align-last: left | right | inside | outside | center | justify| Initial value | left |

setting the following CSS properties:
text-indent: length | percent hanging?| Initial value | 0 |
|---|---|
| Applies to | block containers |
| Inherited | yes |
This property determines the indentation of the first line of text in
the element. If the hanging keyword is added after the
length, a hanging indent will be created by applying the
indentation to every line of text but the first.
text-line-through: color || text-line-through-style| Initial value | none |
|---|---|
| Applies to | all elements |
| Inherited | no |
The text-line-through property is a shorthand for
setting the following CSS properties:
text-line-through-color: color| Initial value | CurrentColor |
|---|---|
| Applies to | all elements |
| Inherited | no |
text-line-through-style: none | solid | dashed | dotted| Initial value | none |
|---|---|
| Applies to | all elements |
| Inherited | no |

| Applies to | block container elements |
| Inherited | no |
text-overline: color || text-overline-style| Initial value | none |
|---|---|
| Applies to | all elements |
| Inherited | no |
The text-overline property is a shorthand for
setting the following CSS properties:

|---|---|
| Applies to | transformable elements |
| Inherited | no |
Please note that the function translate3d() is supported if the
Z (third) coordinate is zero, thus making it equivalent to the 2D translate().
Also note that this property currently does not affect SVG elements - they
need to use their own transform attribute instead (see
Transformations).
transform-origin: [ center | left | right | top | bottom | percent | length ] {1..2}| Initial value | 50% 50% |
|---|---|
| Applies to | transformable elements |
| Inherited | no |
If only one term is given, then the second is assumed to be center.
In particular, if only a percentage or length is given, then it is assumed to be the
horizontal coordinate.
Either one or two coordinates can be given, and if both values are given
as keywords, order doesn't matter; but if two coordinates are given and either
coordinate is a length or percentage, then the horizontal component must come
first: so top 50% is not valid, but top and
top center and 50% top are all valid and equivalent.
unicode-bidi: normal | embed | bidi-override| Initial value | normal |
|---|---|
| Applies to | all elements |
| Inherited | no |
unicode-range: urange+| Initial value | U+0-10FFFF |
|---|---|
| Applies to | @font-face at-rule |
| Inherited |
@font-face {
unicode-range: U+0025-00FF;
}
This CSS at-rule descriptor, used with the
@font-face at-rule,
defines the set of Unicode codepoints that may be supported by the font face
for which it is declared. The descriptor value is a comma-delimited list of
Unicode range (<urange>) values. The union of these ranges defines the
set of codepoints that serves as a hint for user agents when deciding whether
or not to download a font resource needed for the test content of a particular
page.
vertical-align: baseline | sub | super | top | text-top | middle | bottom | text-bottom | length | percent| Initial value | baseline |
|---|---|
| Applies to | inline-level and table-cell elements |
| Inherited | no |
visibility: visible | hidden| Initial value | visible |
|---|---|
| Applies to | all elements |
| Inherited | yes |
This property can be used to make the content of an element invisible.
Unlike using display: none, the element will
still take up space on the page and its descendants may still have
visible content.
white-space: normal | pre | pre-wrap | pre-line | nowrap| Initial value | normal |
|---|---|
| Applies to | all elements |
| Inherited | yes |
widows: integer | percent| Initial value | 1 |
|---|---|
| Applies to | block container elements |
| Inherited | yes |
If a paragraph is split over two pages or columns, this property determines the minimum number of lines that must be left at the top of the second page or column.
The percentage value only applies to Prince for Books, and indicates that one widow line is accepted, as long as the line width is at least the given percentage value of the available page width, to avoid the worst case of having a widow line that is only one or two words long. For more details see Fractional Widows.
width: auto | length | percent| Initial value | auto |
|---|---|
| Applies to | all elements but non-replaced inline elements, table rows, and row groups |
| Inherited | no |
word-break: normal | keep-all | break-all| Initial value | normal |
|---|---|
| Applies to | all elements |
| Inherited | yes |
Prince does not support the value break-word. Use
the value break-all or the property overflow-wrap
with the value break-word instead.
word-spacing: normal | length | percent| Initial value | normal |
|---|---|
| Applies to | all elements |
| Inherited | yes |
writing-mode: horizontal-tb | vertical-rl| Initial value | horizontal-tb |
|---|---|
| Applies to | all elements except table row groups, table column groups, table rows, and table columns |
| Inherited | yes |
Below are the CSS selectors supported by Prince. For their precise definition please refer to the CSS specification - Prince largely implements Selectors Level 4.
selector |
Can refer to a simple selector, compound selector,
complex selector, or selector list. |
selector list |
A comma-separate list of selectors. |
compound selector |
A chain of simple selectors that are not separated by a combinator. |
simple selector |
Either a type selector, universal selector, attribute selector, class selector, ID selector, or pseudo-class. |
relative selector |
A shorthand for selectors that represent elements relative to a :scope
element. |
combinator |
Punctuation that represents a particular kind of relationship between compound selectors on either side. |
An+B |
This micro-syntax to indicate indexes in a list of sibling elements represents
an integer step (A) and offset (B), i.e. it indicates the
An+Bth elements in a list. It also takes the keywords odd
and even. |
expanded element name |
The tuple of local element name and namespace name. |
| Selector List | |
|---|---|
E, F, G |
A comma-separated list of selectors represents all the elements selected by each selector of the list. |
| The Matches-Any Pseudo-class | |
E:matches(s1, s2) |
The matches-any pseudo-class represents an element E that is
represented by the list of compound selectors it takes as argument. |
| The Negation Pseudo-class | |
E:not(s1, s2) |
The negation pseudo-class represents an element E that is not
represented by the list of compound selectors it takes as argument. |
| The Relational Pseudo-class | |
E:has(rs1, rs2) |
The relational pseudo-class represents an element E, if either
of the relative selectors rs1 or rs2, when evaluated
with E as the :scope element, match an element. |
| The Contains Pseudo-class | |
E:contains(foo) |
The contains pseudo-class represents an element E containing the
text foo. |
| Type (tag name) selectors | |
|---|---|
E |
A type selector representing an element E in the default namespace. |
|E |
A type selector representing an element E in no namespace. |
ns|E |
A type selector representing an element E in the namespace ns. |
*|E |
A type selector representing an element E in any or no namespace. |

|* |
A universal selector representing all elements in no namespace. |
ns|* |

Case-sensitivity of the attributes and values depends on the document language.
To match values case-insensitively, the attribute selector may contain the identifier
i before the closing bracket. (Example: [att=val i])
Default namespaces do not apply to attributes. Therefore a namespace ns
that has been previously declared should be added before the namespace separator
| preceding the attribute name.

Below are all of the media queries supported by Prince. For their precise definition please refer to the Media Queries Level 4 specification.
Media queries test how Prince is configured, rather than how the document is styled. The configuration of Prince often depends on the command-line arguments passed to it.
A Media Query is a method of testing certain aspects of the user agent or device that the document is being displayed in.
The syntax consists of an optional media query modifier, an optional media type, and zero or more media features.
Several media queries can be combined into a comma separated media query list.
| Negating a media query | |
|---|---|
not |
An individual media query can be negated by prefixing it with the keyword not. |
| Hiding a media query from legacy user agents | |
only |
Prefixing a media query with the keyword only will have no effect
on the media query's result, but will be ignored by legacy user agents. |
A media type is a category of user-agent devices on which a document may be displayed.
A more fine-grained way of targeting a specific device's exclusive aspects might be to
use media features instead, or in addition. Prince defaults to the media type print.
However, note that the command-line option --media can be used to
set a media type that media queries can test against. This can be convenient if the
person running Prince knows in advance whether the PDF will be printed or viewed on
the screen, such as might be the case for slideshows, or in case one might prefer the author's idea of what screen means.
| Media types | |
|---|---|
all |
Matches all devices. |
print |
Matches printers and devices intended to reproduce or produce a printed display. |
screen |
Matches all devices that are not matched by print or speech. |
speech |
Matches screenreaders and other devices that "read out" a page. |
A media feature is a more fine-grained way of targeting a specific user-agent. Media features use the same syntax as CSS properties. However, there are some differences between the two:
and.Multiple media features may be combined into a media condition using full boolean
algebra (not, and, or).
| Media feature types | |
|---|---|
| discrete | Media features of the type "discrete" take their values from a set. |
| range | Media features of the type "range" take their values from a range. Their feature
names can be prefixed by min- or max-. |

Describes whether the output device is grid (1) or bitmap (0). Prince
is bitmap based, and thus 0 matches. |
| Type: discrete | |
update |
|
Value: none | slow | fast |
Describes the ability of the output device to modify the appearance
of the content once it has been rendered. In Prince the layout cannot be updated, and
thus only none matches. |
| Type: discrete | |
overflow-block |
|
Value: none | scroll | optional-paged
| paged
|
Describes the behavior of the device when content overflows the initial containing block in the block axis.. |
| Type: discrete | |

@import |
In this section you find the documentation for the supported CSS at-rules.
The following at-rules have to appear at the beginning of the CSS document, and exactly in this order:
@charset |
Defines the fallback encoding to use for the stylesheet. Prince supports stylesheets
in UTF-8, UTF-16, Latin1 and Windows-1252. |
@import [ <url(URL)> | <string> ] supports([ <supports-condition> | <declaration> ])?
<media-query-list>? |
Allows authors to import style rules from other style sheets. The url(URL)
or <string> give the URL of the style sheet to be imported, while
the optional supports(...) expression and <media-query-list>
state the import conditions. |
@namespace [Prefix]? [ <url(URL)> | <string> ] |
Defines a namespace prefix or default namespace to be used in the stylesheet. |
After the initial at-rules, the following at-rules can appear also in nested form in the CSS document:
@page [Name] Selectors { Page-declarations } |
|
|---|---|
| Modifies margins, orphans, widows and page breaks of a document when printing it. The pages are identified either by a name, or by a page pseudo-class and page declarations can either be style declarations or page region at-rules. | |
:left |
Page pseudo-classes |
:right |
|
:recto |
|
:verso |
|
:first |
|
:blank |
|
:nth(N) |
|
@left | @left-top | @left-middle |
@left-bottom
|
Page region at-rules |
@right | @right-top | @right-middle |
@right-bottom
|
|
@top | @top-left-corner | @top-left |
@top-center | @top-right | @top-right-corner

@bottom-center | @bottom-right | @bottom-right-corner
|
|
@page-float-top | @page-float-bottom | @prince-overlay
|
|
@footnote |
|
The @page rule takes the following CSS properties:
prince-bleed |
prince-mark-length |
prince-mark-offset |
prince-mark-width |
prince-pdf-page-colorspace |
prince-pdf-page-label |
prince-rotate-body |
prince-shrink-to-fit |
prince-trim |
size
|
|
@media Media-query-list { Rules } |
|---|
| The rules will apply if the device meets the criteria of the condition defined in the media query. See CSS Media Queries for details. |
@supports Condition { Rules } |
|---|
Checks whether particular property:value combinations are supported.
Unlike media queries, this uses the classical two-valued logic. |
@font-face { Font-declarations } |
|
|---|---|
| Links a font family to an actual font. | |
The @font-face rule takes the following CSS descriptors: |
|
font-family: <family-name> |
This descriptor defines the font family name that will be used in all CSS font
family name matching. It is required for the @font-face rule to be valid. |
src: [ url(<URL>) format(<string>#)? | local(<family-name>) |
prince-lookup(<family-name>) ]# |
This descriptor specifies the resource containing font data. It is required for
the @font-face rule to be valid. The local() function searches
for locally installed system fonts, but prince-lookup() will also find
fonts defined by other @font-face rules. |
unicode-range: <urange># |
This descriptor defines the set of Unicode codepoints that may be supported by the font face. The descriptor value is a comma-delimited list of Unicode range values. |
Additionally, @font-face takes the CSS descriptors
font-variant, font-stretch,
font-weight and font-style,

Character entities are a method of including arbitrary characters in XML documents by referencing their UNICODE number rather than writing them directly. CSS has a similar mechanism to include special characters.
This can be convenient when you wish to include characters such as smart quotes, symbols or mathematical operators that do not exist in the character encoding that you are using for your XML documents (such as ASCII or ISO-8859-1 "Latin-1"), or when you want to insert some of these characters into the final layout by means of CSS.
Here is an example of including smart quotes in an XML document using character entities:
XML
<p>
These are “smart quotes” to be precise.
</p>
Output
A typical usecase for character entities in CSS is the
prince-text-replace property, which
replaces a certain character string with another one. In the sample
"Reconstructed Essay"
(HTML -
PDF),
the property is used to replace occurrences of "s" with the "long s" to recreate
the original printed book.
CSS
body {
prince-text-replace: "s" "\017F";
