The Core Style Project proposes a modular architecture for Web style sheets. It builds upon the CSS1 Base Style Sheet incorporated into the CSS2 Recommendation. The project aims to promote cascadability among Web style sheets of diverse origins by providing style authors with generic, yet attractive models and bases for their own elaboration. Shared CSS style sheets offer benefits to Web site developers, content providers, and users alike. Style sheet reuse means less site management and more consistent appearance.
Consistency sends a strong message about corporate identity.
It also improves accessibility by making it easier to navigate the site. Shared styles free content providers from the burden of rewriting style rules for each document. W3C will continue to add to these Core Styles and intends to make css.w3.org a gallery of style sheets contributed by Web designers for communal consumption. The Test Suite will be completed with CSS2 test documents in the near future. Recommendation Process Specifications developed within W3C working groups must be formally approved by the Membership.
