- Discussed F2F logistics; need more topics for agenda
- Discussed interaction of viewport units and scrollbars, and avoiding relayout in ‘overflow: auto’ case. Need to evaluate use cases for viewport units to decide whether ‘auto’ should be laid out as ‘hidden’ or ‘scroll’.
- Discussed issues with Pointer Events spec. Specific concerns include:
- Spec seems to confuse people as currently-written
- The
touch-action property might be overly-specific to touch interfaces
- Discussed whether
touch-action property is necessary.
- Spec should show examples of how
touch-action is used in an all-declarative use case. (If it is only useful when JS is invoked, maybe its behavior should likewise be handled by JS, not by using a declarative property that’s that expects alternate handling via JS.)
- Discussed CSS Masking, progress to LC. Issues raised include:

CSS3 Text Decoration Last Call for Comments
The CSS Working Group has published a Last Call Working Draft of CSS Text Decoration Level 3. Level 3 extends line decorations (underlines, overlines, and strike-throughs) to add controls for color, style, position, and continuity. It also introduces emphasis marks (traditionally used in East Asian typography), and text shadows (which were deferred from Level 2).
Feedback is welcome, especially from people who work with non-Latin writing systems. The deadline for comments is 31 January 2013. As always, please send comments to the (archived) public mailing list www-style@w3.org with the spec code ([css-text-decor-3]) and your comment topic in the subject line. (Alternatively, you can email one of the editors and ask them to forward your comment.)
CSS3 Cascading and Inheritance WD Updated!
The CSS Working Group has published an updated Working Draft of CSS Cascading and Inheritance Level 3. This is the first update to this module since 2005. In addition to synchronizing the module with CSS2.1, the update proposes a new all shorthand for resetting all properties, a CSS-wide default keyword for rolling back the cascade, and scoped rules to the cascade. Feedback is welcome, especially on Chapter 4.
As always, please send comments to the (archived) public mailing list www-style@w3.org with the spec code ([css3-cascade]) and your comment topic in the subject line. (Alternatively, you can email one of the editors and ask them to forward your comment.)

CSS3 Writing Modes Was Updated
Forgot to announce that CSS Working Group has published an updated Working Draft of CSS Writing Modes Level 3 back in November. CSS Writing Modes Level 3 defines CSS support for various international writing modes, such as left-to-right (e.g. Latin or Indic), right-to-left (e.g. Hebrew or Arabic), bidirectional (e.g. mixed Latin and Arabic) and vertical (e.g. Asian scripts).
We’re hoping this is the last round before Last Call, but to get there we need your help! Please review the draft and give us feedback. Changes since the last Working Draft are listed in the Changes section. Sections that particularly need review and feedback include logical directions, orthogonal flows, and tate-chu-yoko.
As always, please send feedback to the (archived) public mailing list www-style@w3.org with the spec code ([css3-writing-modes]) and your comment topic in the subject line. (Alternatively, you can email one of the editors and ask them to forward your comment.)
CSS Fonts Level 3 Updated
Just a quick note to announce that a new working draft of the CSS3 Fonts spec was published this week.
Significant changes/additions include:
As always, please post any and all comments, preferably well-reasoned, insightful ones, to (archived) public mailing list www-style@w3.org with the spec code ([css3-fonts]) and your comment topic in the subject line.
CSS3 Conditional Rules (@supports) Last Call
The CSS Working Group has published a Last Call Working Draft of CSS3 Conditional Rules. This module defines the existing @media rule for media-specific parts of style sheets, which use media queries as a condition syntax, and introduces the new @supports rule for parts of style sheets that are specific to implementations that support particular property:value pairs. It also defines associated APIs.
This is a Last Call Working Draft; the working group hopes to advance this module to Candidate Recommendation soon after the last call period ends on January 10. If there’s anything you believe
needs to be changed anywhere in the specification, you should say so now. Changes since the last Working 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 (>>[css3-conditional]<<) and your comment topic in the subject line. (Alternatively, you can email the editor and ask him to forward your comment.)

- Discussed Flexbox issue wrt stretch-sizing elements with aspect ratio.
- Discussed Animations terminology for Bug 16116.
- Resolved: Transitions defines the timing functions, Animations has normative dependency on Transitions for them. (Bug 14784)
- Resolved: Animations only “run” (fire start events, etc) if they have at least one valid keyframe. (Bug 15251)
- Resolved: When an element changes from
display:none to display: <non-none>, animations start immediately. (Bug 14785)
- Resolved: An initially-paused animation is still started (fires start events, etc.) (Bug 14774)
- Resolved: Animations can be paused during their delay phase, which freezes the remaining delay to be applied after it unpauses. (Bug 14774)
- Resolved:
animation-play-state is not in the shorthand on purpose (Bug 14787)
- Resolved:
animation-play-state has the same list behavior as the other animation properties: matching the length of animation-name. (Bug 14786)
- Resolved: Look into “adjacent keyframes” for level 4, but not for the current level. (Bug 20092
– Discussed motivations and problems with Florian’s media query proposal, along with conceptual framework for extending Media Queries in level 4.

- Discussed February F2F logistics.
- Objection to publishing CSS3 Text LC before next F2F.
- Resolved: Publish CSS3 Fonts WD
- Resolved: No exceptional zeroing of negative margins for flex items.
- Resolved: Min/max clamping step of resolving flexible lengths does not pass cross-size limits through aspect ratio into main size flex computations.
- Various Flexbox clarifications reviewed: Set A, Set B, Set C.
- Issue on handling aspect ratio during main size computations still being worked out. See thread and proposed changes.
- Discussed case-sensitivity of CSS identifiers. Internationalization Working Group recommends Unicode case-folding. Anne van Kesteren recommends ASCII-folding. Points brought up:
- Some implementations seem to do some form of Unicode case-insensitivity for class name matching. Some do ASCII-only.
- HTML spec requires ASCII-folding only for its case-insensitivity.
- ASCII-folding is easier to implement correctly.
- ASCII-folding is really weird for non-English languages with case.
- Previous uses of case-insensitivity were ASCII-only idents, where this wasn’t a usability issue.
No conclusions yet.
