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 15 September 2011, the CSSWG officially published a new module: CSS Device Adaptation. This specification provides a way for an author to specify, in CSS, the size, zoom factor, and orientation of the viewport that is used as the base for the initial containing block. It is a CSS replacement for the proprietary HTML meta viewport tag.
As always, please send feedback to www-style with the spec code [css3-values]
and your comment topic in the subject line.
