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 Cascading and Inheritance Level 3. This is the first update to this module since 2005. In addition to synchronizing the module with CSS2.1, the update proposes a new
all shorthand for resetting all properties, a CSS-wide
default keyword for rolling back the cascade, and scoped rules to the cascade. Feedback is welcome, especially on Chapter 4.
As always, please send comments to the (archived) public mailing list firstname.lastname@example.org with the spec code (
[css3-cascade]) and your comment topic in the subject line. (Alternatively, you can email one of the editors and ask them to forward your comment.)
