[CSSWG][mediaqueries-4] Last Call for Comments on Media Queries Level 4

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 at:


Please review the draft, and send any comments to this mailing list,
<www-style@w3.org>, prefixed with [mediaqueries-4] (as I did on this
message) or (preferably) file them in the GitHub repository at

For the CSS WG,
—Florian Rivoal
