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 a Last Call Working Draft of CSS Syntax Module Level 3. This module describes, in general terms, the basic structure and syntax of CSS stylesheets. It defines, in detail, the syntax and parsing of CSS – how to turn a stream of bytes into a meaningful stylesheet.
Since the previous Working Draft, the concept of environment encoding has been added. This does not affect implementation, it only helps to move some definitions to other specifications where they belong.
Changes since the last Working Draft are listed in the Changes section.
Additionally, since this Last Call Working Draft, the Serialization section has been rewritten in the Editor’s Draft to make only the round-trip requirement normative, and move the details of how to achieve it into a note. Some corner cases in these details have been fixed. Please also review it as well.
As always, please send feedback to the (archived) public mailing list firstname.lastname@example.org with the spec code (
[css-syntax]) and your comment topic in the subject line. (Alternatively, you can email one of the editors and ask them to forward your comment.)
