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 CSS Media Queries as a Proposed Recommendation. Media Queries allows authors to tailor the style that they want to apply to a document based on characteristics of the environment the document is being rendered in.
As always, please send feedback to the (archived) public mailing list firstname.lastname@example.org (see instructions). When sending e-mail, please put the text
[css3-mediaqueries] in the subject (alternatively you can email one of the editors and ask them to forward your comment).
