Three drafts published by the CSS Working Group

11 September 2012

The Cascading Style Sheets (CSS) Working Group has published three Working Drafts  .

• CSS Conditional Rules Module Level 3. This module contains the features of CSS for conditional processing of parts of style sheets, conditioned on capabilities of the processor or the document the style sheet is being applied to. It includes and extends the functionality of CSS level 2, which builds on CSS level 1. The main extensions compared to level 2 are allowing nesting of certain at-rules inside '@media', the addition of the '@supports' and '@document' rules for conditional processing.
• CSS Image Values and Replaced Content Module Level 4. This module contains the features of CSS level 4 relating to the <image> type and replaced elements. It includes and extends the functionality of CSS Image Values and Replaced Content Module Level 3. The main extensions compared to level 3 are several additions to the ‘<image>’ type, additions to the ‘<gradient>’ type, extensions to the ‘image()’ function, definitions for interpolating several ‘<image>’ types, and several properties controlling the interaction of replaced elements and CSS's layout models.
• CSS Transforms. CSS transforms allows elements styled with CSS to be transformed in two-dimensional or three-dimensional space. This specification is the convergence of the CSS 2D transforms, CSS 3D transforms and SVG transforms specifications.
