Review of Media Queries 4 requested

Dear everybody,

The number of open issues [1] on Mediaqueries Level 4 [2] is approaching =
zero. As the editor of that specification, I anticipate that fairly =
soon, after the remaining open issues have been resolved, I will ask the =
CSS-Working-Group to publish an updated CR.

Therefore, I would like to encourage review by anyone with an interest =
in this specification. The previous CR [3] is from 5 September 2017, and =
there has been a fairly limited amount of changes since then. The =
Changes section [4] is up to date, and a disposition of the comments =
received since that previous CR is available [5].

As a reminder from the specification's abstract:

> 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.
>=20
> 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.


The preferred way of sending feedback is to file issues at =
https://github.com/w3c/csswg-drafts/issues, using [mediaqueries-4] in =
the title. To make tracking and addressing issues easier, a separate =
issue for each problem to be addressed is preferred over a large issue =
describing all concerns found during a review.

At this point, the feature-set of this level 4 draft is intended to be =
stable, and additional features are being developed in Mediaqueries =
Level 5 [6]. Requests for additional features, if any, should be filed =
in the same github repository, but should use [mediaqueries-5] in the =
title.

Best regards,
