The background-attachment property determines the origin
of the coordinate system for background images. The default value of
scroll will position background images based on an origin
at the top-left corner of the padding area of the current element,
while a value of fixed places the origin at the top-left
corner of the page box.
Note that the background-attachment property only changes
the origin of the coordinate system used to position the image; the
background image will still only be shown within the padding area of
the current element.
