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.

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.

getParentStyleSheet

CSSStyleSheet getParentStyleSheet()
The style sheet that contains this rule.


getParentRule

CSSRule getParentRule()
If this rule is contained inside another rule (e.g. a style rule inside an @media block), this is the containing rule. If this rule is not nested inside any other rules, this returns null.
