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.
On 12 July 2011 Anne van Kesteren pushed out a First Public Working Draft of the CSS Object Model
[cssom] specification. The primary goal of the spec is to standardize various un(der)specified-but-implemented APIs for interacting with CSS style sheets and drive the Web platform towards interoperability in this area.
A second goal for the CSSOM effort is to provide better APIs for interacting with style sheets. To that end, Daniel Glazman has put out a call for suggestions to find out what problems the CSSOM APIs most need to solve.
Anne also published an update to the CSSOM View Module
[cssom-view]. The main thing holding this module back is the lack of feedback, particularly from implementers, so please send comments!
As always, send feedback to www-style with the appropriate
[spec-code] and your comment topic in the subject line.
