The Cascading Style Sheets (CSS) Working Group has published a Last Call Working Draft of CSS Syntax Module Level 3. This module describes, in general terms, the basic structure and syntax of CSS stylesheets. It defines, in detail, the syntax and parsing of CSS – how to turn a stream of bytes into a meaningful stylesheet. CSS is a language for describing the rendering of structured documents (such as HTML and XML) on screen, on paper, in speech, etc. Comments are welcome through 17 December.
