The Protocols and Formats Working Group is no longer chartered to operate. Its work will continue in two new Working Groups:

  • https://www.w3.org/WAI/APA/ Accessible Platform Architectures, to review specifications, develop technical support materials, collaborate with other Working Groups on technology accessibility, and coordinate harmonized accessibility strategies within W3C; and
  • https://www.w3.org/WAI/ARIA/ Accessible Rich Internet Applications, to continue development of the Accessible Rich Internet Applications (WAI-ARIA) suite of technologies and other technical specifications when needed to bridge known gaps.

Resources from the PFWG remain available to support long-term institutional memory, but this information is of historical value only.

This Wiki page was edited by participants of the Protocols and Formats Working Group. It does not necessarily represent consensus and it may have incorrect information or information that is not supported by other Working Group participants, WAI, or W3C. It may also have some very useful information.

CSS/Spec Review

From Protocols and Formats Working Group Wiki
Jump to: navigation, search

This is a tracking page for a comprehensive PFWG review of CSS. Most of CSS active development is in Level 3, so that is what applies unless otherwise indicated. The CSS Working Group maintains a CSS Current Work page that lists most of the modules with status and priority. Additional modules were found in the CSS Editors' Drafts repository, but lack accurate information on status and priority. Some modules were listed in the current work page but no draft could be found. Links to drafts in the table below reference the editors' draft when one could be found, otherwise the TR draft.

The set of documents below is arranged in a suggested priority order, which combines document maturity, CSS priority, and a categorization of the nature of the document. Categories used, in priority order, are:

  1. flow: flow control of objects
  2. layout: overall layout control of page
  3. display: general display functions
  4. aural: auditory control
  5. text: direct control of text presentation
  6. effects: altering appearance of (usually graphical) objects
  7. generated: generated content
  8. syntax: lexical rules
  9. model: processing rules
  10. profile: subsets for particular uses
