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.

Since:
1.4, DOM Level 2

      Throws:
      DOMException - SYNTAX_ERR: Raised if the specified CSS string value has a syntax error and is unparsable.
      INVALID_MODIFICATION_ERR: Raised if the specified CSS string value represents a different type of rule than the current one.
      HIERARCHY_REQUEST_ERR: Raised if the rule cannot be inserted at this point in the style sheet.
      NO_MODIFICATION_ALLOWED_ERR: Raised if the rule is readonly.
