Grids

Microsoft presented another layout proposal that deals with grids. There is a lot of overlap with Template.

CSS3 Writing Modes

Aharon and fantasai explained the new ‘isolate’ and ‘plaintext’ values for ‘unicode-bidi’, what use cases they solve, and how they interact with HTML5’s bidi features.
fantasai explained the new ‘writing-mode’ property and its relationship to SVG; why it does not set the ‘direction’ property, and why the value names were changed
Resolved: remove the horizontal-bt value of ‘writing-mode’
Briefly reviewed ‘text-orientation’ property
Discussed tate-chu-yoko feature requirements.

Minutes and Resolutions TPAC F2F 2010 Monday Afternoon: MultiCol, Flexbox, GCPM

CSS3 Multi-Column Layout

Resolved: If a columnspanning element doesn’t fit within the multicol element without overflowing, then it doesn’t span anymore.
Resolved: column-span applies to “in-flow block-level elements”
Resolved: column-spanning elements are BFC roots always
Resolved: Initial value of column-span is ‘none’ (to distinguish BFC behavior of 1-spanning and not-spanning).
Resolved: Columns overflowing due to forced breaks and not constrained height overflow to the right, rather than wrapping to a new column row below. Note this causes dataloss when printing.

Flexbox

Resolved: Change prefix from box- to flex-
Resolved: Combine box-orient and box-direction into flex-direction
Resolved: Split box-flex into flex-grow and flex-shrink
Resolved: ‘auto’ margins flex as 1
Resolved: Drop box-flex-group
Resolved: Mark multiline at-risk.
Resolved: Rename box-ordinal-group to either flex-order or flex-index (mark exact name as issue)
Resolved: Mark entire transverse alignment as an issue until further notice.

GCPM

Discussed problem of specially styling pages that are the first or last page of a named page set, or that belong to the spread containing that first or last page.
Discussed problem of tweaking page size to handle widows or orphans.
Discussed hyphenate-last-line-avoid property proposal.

CSS2.1 Editor’s Draft now public

By fantasai October 21, 2010 (Permalink)
Categories: publications

In response to the CSSWG resolution, Bert just published a public copy of the CSS2.1 Editor’s Draft on the W3C website.

Most of the resolutions from the CSS2.1 Issues list are reflected in this document, but not all. It will in general be somewhat behind the issues list. It will match the published errata, however. It essentially provides an easier-to-read document that combines the latest official Working Draft with the latest published errata.

We expect the editor’s draft to make life easier for developers and testers working with the CSS2.1 spec, and hope that the official draft will be ready to republish soon.
