CSS Basic User Interface Draft Updated

By Florian Rivoal May 20, 2015 (Permalink)
Categories: publications

The CSS Working Group has published an updated Working Draft of CSS Basic User Interface Module Level 3 (CSS3 UI). This module describes CSS features which enable authors to style user interface related properties and values.

All known issues have been resolved, and the CSS Working Group invites everyone interested in this topic to do a complete review of this draft (under the old process this draft would be another last call).

Barring significant issues, we expect to publish this document as CR in 4 weeks (2015/06/18), with changes that are only non-normative, editorial, dropping of at-risk features, or at most resolutions for minor issues.

Significant changes since the previous draft are listed in the Changes section.

As always, please send feedback to the (archived) public mailing list www-style@w3.org with the spec code ([css-ui]) and your comment topic in the subject line. (Alternatively, you can email one of the editors and ask them to forward your comment.)

CSS Flexbox Level 1 Update, Call for Comments

By fantasai May 15, 2015 (Permalink)
Categories: publications

The CSS Working Group has published an updated Last Call of CSS Flexible Box Layout Level 1 to fold in feedback from the last LCWD. Flexbox is a new layout model for CSS: the contents of a flex container can be laid out in any direction, can be reordered, can be aligned and justified within their container, and can “flex” their sizes and positions to respond to the available space. This is an update, mostly to fix various errors reported against the last draft. As before, the CSSWG is not revoking the call for implementations: we’re just issuing an LCWD to process the changes.

To help with review and with correctly updating implementations, exact diffs since the previous Last Call Working Draft and since the original Candidate Recommendation, and their justifications, are available in the Changes section. A Disposition of Comments is also available. The Last Call comment period ends 11 June 2015.

We are particularly looking for feedback from authors on the percentage margins issue, and will accept comments posted through that post on CSS3.info.

And as usual, we will welcome and track any feedback to the (archived) public mailing list www-style@w3.org with the spec code ([css-flexbox]) and your comment topic in the subject line. (Alternatively, you can email one of the editors and ask them to forward your comment.)

Flexbox and Grid Percentage Margins: Feedback Needed

By Tab Atkins Jr. May 5, 2015 (Permalink)
Categories: Feedback

The CSS Working Group has reached an impasse on the issue of percentage margins (and padding) in flex and grid layout, and needs your input to help decide it.

Option 1: Flex and grid items resolve percentages in margin-top and margin-bottom against the height of the element’s containing block.

Option 2: Flex and grid items resolve percentages in margin-top and margin-bottom against the width of the element’s containing block.

Option 1 makes vertical margins consistent with horizontal margins (which resolve percentages against the width of the element’s containing block). This is a theoretically simpler model, and works well with Flexbox and Grid’s dimension-agnostic layout concepts. However, it is inconsistent with CSS block layout, and causes the margins to collapse to zero when used in an auto-height container.

Option 2 is consistent with the behavior of vertical margins in block and table layout. It has usable behavior in auto-height boxes, and enables the “aspect ratio hack”. However, it is a less obvious behavior, and means the layout interactions change based on whether a flexbox is “row” or “column”.

(For more background, see discussion on www-style.)

We’re looking for comments from authors explaining which behavior they think is better for Flex and Grid layout, and why. Do you have use-cases that can only be achieved with one behavior or the other? Show us in a comment on CSS3.info!
