Raw Message
The CSS WG has published its hopefully last Working Draft of the
CSS Box Alignment Module Level 3:

https://www.w3.org/TR/css-align-3/

This module contains the features of CSS relating to the alignment
of boxes within their containers in the various CSS box layout models:
block layout, table layout, flex layout, and grid layout.

This is the last call for comments, as we plan to request a transition
to CR in two weeks unless issues are brought up or anyone specifically
requests more time for review.

Wrt i18n, the alignment values are expressed in flow-relative (writing-mode
responsive) directional terms, so we don't anticipate any problems there.
Baseline alignment, despite its simple invocation, is very complicated,
however: we've done our best to handle all the various script and writing
mode combinations.

Wrt a11y, the alignment values just shift things around slightly on the
screen; there is no visual reordering or re-arrangement of any elements,
nor any interaction, color, or time-based considerations, so we don't
anticipate any a11y issues.

Changes since the last draft are listed at:
https://www.w3.org/TR/2017/WD-css-align-3-20170515/#changes
and consist of some syntactic changes, deferring features to L4, and some
minor behavioral tweaks.

If you need more time to review, please let us know. Otherwise, please send
any comments to our mailing list, <www-***@w3.org>, prefixed with
[css-align] (as I did on this message) or (preferably) file them in the GitHub
repository at
https://github.com/w3c/csswg-drafts/issues

For the CSS WG,
