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 WG looked, among other things, at the stability of the Backgrounds and Borders module and an issue with replaced elements and ‘run-in’ in CSS 2.1.
There was also news about Selectors: after seeing the number of implementations, the Director agreed to give the specification Proposed Recommendation status. The review period will start in a few days.
