This is a page from the Cascading Style Sheets Working Group Blog. Some other places to find information are the “current work” page, the www-style mailing list, the Future of CSS syndicator, and the issue list on Github.
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 has published two back-to-back Working Drafts of the CSS Box Model Module Level 3. The first publication archives Bert and Anton’s changes to that spec since the 2007 draft for archaeological purposes. (Note: It is still dangerously out-of-date, please continue to reference CSS2.) The second publication cuts the module down to a subset of CSS2 Chapter 8.
The scope of this module is now just the margin and padding properties. We have dropped all of the spec content that discusses box generation (moved to the CSS Display Module) or the Flow Layout model (will become its own module based on the prose in CSS2—which has been maintained—rather than what was in earlier publications—which was not). The remaining content, which discusses the box model (margin/padding/border/content areas) has been synced to CSS2. See Introduction. There are no non-editorial changes since CSS Level 2, other than adapting the prose slightly to account for vertical writing modes.
A future revision of this module might include the border styling properties (currently defined in CSS Backgrounds and Borders); whether or not to move them is currently open question, thoughts on this idea welcome.
Please send feedback by either filing an issue in GitHub (preferable) or sending mail to the (archived) public mailing list www-style@w3.org with the spec code ([css-box-3]) and your comment topic in the subject line. (Alternatively, you can email one of the editors and ask them to forward your comment.)
