The CSS WG has published a Candidate Recommendation Draft and invites implementations of the Media Queries Level 4:

    https://www.w3.org/TR/mediaqueries-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.

Media Queries Level 4 describes the mechanism and syntax of media queries, media types, and media features. It extends and supersedes the features defined in Media Queries Level 3, and marks a shift from attempting to categorize different devices into distinct media types to describing them through media features.

This republication of MQ4 is a minor update to publish some editorial tweaks and to correct an issue in the syntax description.

Significant changes through various versions are listed at:

  https://www.w3.org/TR/2021/CRD-mediaqueries-4-20211225/#changes

Implementors are encouraged to complete their support for the features described in this specification and to contribute to the test suite.

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
  https://github.com/w3c/csswg-drafts/issues

For the CSS WG,
—Florian
