Interface CSSRule

All Known Subinterfaces:
CSSCharsetRule, CSSFontFaceRule, CSSImportRule, CSSMediaRule, CSSPageRule, CSSStyleRule, CSSUnknownRule

public interface CSSRule

The CSSRule interface is the abstract base interface for any type of CSS statement. This includes both rule sets and at-rules. An implementation is expected to preserve all rules specified in a CSS style sheet, even if the rule is not recognized by the parser. Unrecognized rules are represented using the CSSUnknownRule interface.

See also the Document Object Model (DOM) Level 2 Style Specification.
