Updated CR of the CSS Containment Module Level 1

By Florian Rivoal May 24, 2018 (Permalink)
Categories: publications

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 update to the previous CR brings bug fixes and clarifications. No new feature has been added, nor has any feature been removed. All changes since the previous CR come with a test in Web Platform tests.

Significant changes sine the last CR are listed in the Changes section. A disposition of comments is 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.)

CSS Grid Level 2 Updates: Per-axis Grid and ‘ar’ units for gutters

By fantasai April 27, 2018 (Permalink)
Categories: publications

The CSS Working Group has published an updated Working Draft of CSS Grid Level 2. Level 2 expands Grid by adding “subgrid” capabilities for nested grids to participate in the sizing of their parent grids; and aspect-ratio–controlled gutters.

The main goal of this level is to have a completed spec for subgrids as soon as possible—so while we might cull some other minor features from the list of requests, more complex feature requests will be deferred to Level 3. Changes from the last draft consist mainly of dropping the simplified “dual-axis” subgrid proposal in favor of the more powerful “per-axis” proposal and switching the syntax for aspect-ratio–controlled gutter justification to use ar units in place of bare numbers. We’ll be working through individual issues filed against these features going forward, such as control over gaps and interaction of parent/subgrid named lines, etc.

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-grid-2]) and your comment topic in the subject line. (Alternatively, you can email one of the editors and ask them to forward your comment.)

CSS Box Alignment Level 3 Updated WD

By fantasai April 23, 2018 (Permalink)
Categories: publications

The CSS Working Group has published an updated Working Draft of CSS Box Alignment Level 3.This module contains the features of CSS relating to the alignment of boxes within their containers in the various CSS box layout models: block layout, table layout, flex layout, and grid layout. It also includes the new cross-module gap properties (row-gap, column-gap, gap).

This update fixes various errors in the previous draft. At this point only one issue is open, and the biggest known problem is an insufficient number of illustrations, particularly in the baseline alignment sections. Other than that, we’re hoping we can wrap up and request a transition to CR soon. Changes since the last Working Draft are listed in the Changes section.

Special thanks to Melanie Richards for adding illustrations to the Positional Alignment section, especially as they were unexpectedly tricky to diagram due to internationalization-related complexities. Further editorial advice and/or diagrams that would help make this draft easier to understand are very welcome.

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-align-3]) and your comment topic in the subject line. (Alternatively, you can email one of the editors and ask them to forward your comment.)

CSS Display Level 3 Update

By fantasai April 20, 2018 (Permalink)
Categories: publications

The CSS Working Group has published an updated Working Draft of CSS Display Level 3. CSS Display describes how the CSS formatting box tree is generated from the document element tree and defines properties that control the types of boxes thus generated.

Changes this time around are fairly minor, mostly just tightening up definitions; see the Changes section. There are a handful of open issues, mostly editorial, but otherwise we expect (hope?) the draft will transition to CR in roughly its current form pretty soon.

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-display-3]) and your comment topic in the subject line. (Alternatively, you can email one of the editors and ask them to forward your comment.)
