## Detailed Description

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 it is not recognized. Unrecognized rules are represented using the `CSSUnknownRule` interface.

## Member Enumeration Documentation

enum DOM::CSSRule::RuleType

| An integer indicating which type of rule this is. Definition at line 68 of file css_rule.h.

## Member Function Documentation

unsigned short CSSRule::type | ( |  | ) | const

| 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` . Definition at line 60 of file css_rule.cpp.

DOMString CSSRule::cssText | ( |  | ) | const

| The parsable textual representation of the rule. This reflects the current state of the rule and not its initial value. Definition at line 66 of file css_rule.cpp.

void CSSRule::setCssText | ( | const DOM::DOMString & |  | ) |

see cssText

Exceptions:

  DOMException | HIERARCHY_REQUEST_ERR: Raised if the rule cannot be inserted at this point in the style sheet.

NO_MODIFICATION_ALLOWED_ERR: Raised if this style sheet is readonly.

Exceptions:

  CSSException | 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.

Definition at line 72 of file css_rule.cpp.

CSSStyleSheet CSSRule::parentStyleSheet | ( |  | ) | const

| The style sheet that contains this rule. Definition at line 78 of file css_rule.cpp.

CSSRule CSSRule::parentRule | ( |  | ) | const

| If this rule is contained inside another rule (e.g. a style rule inside an block), this is the containing rule. If this rule is not nested inside any other rules, this returns `null` . Definition at line 84 of file css_rule.cpp.
