Updated CR of CSS Contain

By Florian Rivoal February 4, 2019 (Permalink)
Categories: publications

(This should have been published much earlier. Apologies for the belated announcement).

The CSS WG has published a Candidate Recommendation and invites implementations of the CSS Containment Module Level 1.

This CSS module describes the contain property, which indicates that the element’s subtree is independent of the rest of the page. This enables heavy optimizations by user agents when used well.

This is a minor update, driven by implementation experience and testing, focused on bug fixing and clarifications. Barring anything unexpected, the CSS-WG expects little to no change after this. People who intend to review this specification but have not yet had the chance to do so are strongly encouraged to look at it as soon as possible, as implementations are progressing, and growing usage in the wild will increasingly limit possible changes.

Significant changes are listed in the change section. A comprehensive test suite for the full specification was developed. A Disposition of Comments is also available.

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 ([css-contain]) and your comment topic in the subject line. (Alternatively, you can email one of the editors and ask them to forward your comment.)

Updated CR of CSS Scroll Snapping Level 1

The CSS Working Group has published an updated Candidate Recommendation of CSS Scroll Snapping Module Level 1. This module contains features to control panning and scrolling behavior with “snap positions”.

The Changes are just fixing some errors in the previous draft. See also Disposition of Comments.

Please send any further 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 ([css-scroll-snap-1]) and your comment topic in the subject line. (Alternatively, you can email one of the editors and ask them to forward your comment.)

Updated <‘property’> notation in Value Definition Syntax

By fantasai January 31, 2019 (Permalink)
Categories: publications

The CSSWG just published updates to CSS Values and Units Level 3 and CSS Values and Units Level 4 redefining the <'property'> notation, which represents the value space of a property for re-use in other syntax definitions, to exclude any top-level #-multiplier. (See §2 Value Definition Syntax.)

The reason for this change it to make it easier to define syntax for list-valued properties and shorthands: for example, previously <'background-clip'> would represent [ border-box | padding-box | content-box ]# (a list of keywords), which precluded re-using it in defining the background shorthand syntax. Now that the top-level #-mark is ignored when importing syntaxes this way, shorthands of list-valued properties and other patterns which extend an existing value set become much easier to describe.

The full list of changes since the previous CR update can be found in the Changes section, and a Disposition of Comments is also available. (There were no substantive changes to Level 4 other than copying over the Level 3 changes.)

Please send any 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 ([css-values]) and your comment topic in the subject line. (Alternatively, you can email one of the editors and ask them to forward your comment.)
