Do you want to know how the CSS WG works? Fantasai has written about:csswg, An Inside View of the CSS Working Group at W3C.
The CSS Working Group has published an updated Working Draft of CSS Writing Modes Level 3. This CSS module covers bidirectional text and vertical text layout.
The primary changes in this update are to integrate references to Unicode Technical Report #50 (which will define the default orientation of all Unicode characters) and to adjust the algorithm for auto sizing in orthogonal flows to account for the size of the containing block. Significant changes since the last Working Draft are listed in the Changes section.
As always, please send feedback to the (archived) public mailing list firstname.lastname@example.org with the spec code (
[css3-writing-modes]) and your comment topic in the subject line. (Alternatively, you can email one of the editors and ask them to forward your comment.)
