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 its hopefully last Working Draft of Media Queries Level 4.
Media Queries allow authors to test and query values or features of the user agent or display device, independent of the document being rendered. They are used in the CSS @media rule to conditionally apply styles to a document, and in various other contexts and languages, such as HTML and Javascript.
Level 4 extends and supersedes the features defined in Media Queries Level 3. It brings significant improvements on the syntax, and a shift from using media types to finer-grained media features.
This is the last call for comments, as we plan to request a transition to CR at the end of June unless issues are brought up or anyone specifically requests more time for review.
Significant changes since Media Queries 3 are listed in the Changes section.
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 ([mediaqueries-4]) and your comment topic in the subject line. (Alternatively, you can email one of the editors and ask them to forward your comment.)
