The W3C CSS Working Group has published Cascading Style Sheets (CSS) Snapshot 2007. "When the first CSS specification was published, all of CSS was contained in one document that defined CSS Level 1. CSS Level 2 was defined also by a single, multi-chapter document. However for CSS beyond Level 2, the CSS Working Group chose to adopt a modular approach, where each module defines a part of CSS, rather than to define a single monolithic specifcation. This breaks the specification into more manageable chunks and allows more immediate, incremental improvement to CSS. Since different CSS modules are at different levels of stability, the CSS Working Group has chosen to publish this profile to define the current scope and state of Cascading Style Sheets as of late 2007. This profile includes only specifications that we consider consider stable and for which we have enough implementation experience that we are sure of that stability. Note that this is not intended to be a CSS Desktop Browser Profile: inclusion in this profile is based on feature stability only and not on expected use. This profile defines CSS in its most complete form."
