The @page margin-bottom must be big enough to fit the footer content.

I'm add footer like this. I need fix margin from bottom
@page :nth(1) {
@bottom {
content: flow(footer);
margin-bottom: 20px;
}
}

#footer-template {
flow: static(footer)
}

<div id="footer-template">(dynamic text from PHP)</div>

But if text have dynamic number of lines, some of line is cut.

You need @page { margin-bottom: ... } to be big enough to hold all the text.

But this text add dynamically, and i don't know what margin-bottom be enough

In that case I'm afraid it will be necessary to use a different mechanism than margin boxes, perhaps a page float instead with "float: bottom".

If you know the maximum number of lines, you simply can make the bottom margin box high enough to fit the maximum number of lines, which may appear, and then just align the text within the margin box.
