CSS Cascading and Inheritance Level 4 Draft Published

The Cascading Style Sheets (CSS) Working Group has published a Working Draft of CSS Cascading and Inheritance Level 4. This CSS module describes how to collate style rules and assign values to all properties on all elements. By way of cascading and inheritance, values are propagated for all properties on all elements. One of the fundamental design principles of CSS is cascading, which allows several style sheets to influence the presentation of a document. When different declarations try to set a value for the same element/property combination, the conflicts must somehow be resolved.
