The CSS WG has published a Candidate Recommendation and invites implementations of the CSS Basic UI Module Level 3:

    https://www.w3.org/TR/css-ui-3/

This specification includes and extends user interface related features from the properties and values of CSS level 2 revision 1. It uses various properties and values to style basic user interface elements in a document.

This document is intended to be essentially complete, and pending approval of a few recently submitted tests, will have an exhaustive test suite, most of which already passes in two or more implementations. Implementors are encouraged to look through the test suite and to fix areas where they are not yet conforming. Unless this last effort uncovers some unexpected problem, this specification should to move to PR and REC relatively soon.

However, CSS-WG would like to draw attention one feature which is at risk of being postponed or dropped: Directional Focus Navigation (https://www.w3.org/TR/css-ui-3/#nav-dir). This feature is not implemented in any current desktop or mobile browser. One known implementation is the defunct Presto engine by Opera Software. It is also known that TV browsers, especially UAs conforming to HbbTV use this feature, but the state of these implementations is unknown. The CSS-WG encourages TV manufacturers, software vendors for these platforms, or anyone else with an implementation to get in touch, so that we can evaluate how many independent implementations there are, and how conforming they are. In the absence of this information, it is likely that this feature will be postponed.

message) or (preferably) file them in the GitHub repository at
