Interface CSSRule

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:
DOM Level 2

getCssText

public String getCssText()
The parsable textual representation of the rule. This reflects the current state of the rule and not its initial value.

getParentRule

public 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.

getParentStyleSheet

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

getType

public short getType()
The type of the rule, as defined above. The expectation is that binding-specific casting methods can be used to cast down from an instance of the CSSRule interface to the specific derived interface implied by the type.

public void setCssText(String cssText)
            throws DOMException
The parsable textual representation of the rule. This reflects the current state of the rule and not its initial value.

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.
