Status of display-align

[Peter B. West]

I need to push a block to the bottom of the page. In 0.94 I've tried display-align="after" on a block-container with either height="100%" or block-progression-dimension="100%", and on a table-row. These don't seem to work.

What is the recommended procedure, if any, for achieving this in 0.94 (or 0.95beta)?

I'd recommend space-before:
    <fo:flow flow-name="xsl-region-body">
      <fo:block>Hello World!</fo:block>
      <fo:block space-before.optimum="30cm" space-before.minimum="0mm">This
block is aligned at the bottom of the page!</fo:block>
    </fo:flow>

You make the optimum space-before quite big but allow it to shrink. The
layout algorithm will do the rest. Unfortunately, using percentages in
block-progression-direction doesn't work reliably, yet (as you noticed).
So you can't specify space-before.optimum="100%". The spec also says:
"Percentages: N/A (Differs from margin-bottom in CSS)". Just use a "big"
absolute length.

Furthermore, there are the display-align extensions proposed by Luca
Furini a few years ago. But I don't think this works anymore because we
don't test for it.

Jeremias,

Your hopes were realised.

On my first attempt I put, automatically, space-before.maximum and space-before.minimum. I took me a lot of fiddling around in the wrong places before I read this message again more carefully.

Thanks,
Peter
