Abstract

This module contains the features of CSS for conditional processing of parts of style sheets, based on capabilities of the processor or the environment the style sheet is being applied in. It includes and extends the functionality of CSS Conditional 3 [css-conditional-3], adding the ability to query support for particular selectors [SELECTORS-4] through the new selector() notation for supports queries.
