                CSSRule

Known Subclasses:
  csscharsetrule.CSSCharsetRule, csscomment.CSSComment, cssmediarule.CSSMediaRule, cssnamespacerule.CSSNamespaceRule, csspagerule.CSSPageRule, cssstylerule.CSSStyleRule, cssunknownrule.CSSUnknownRule, cssimportrule.CSSImportRule, cssfontfacerule.CSSFontFaceRule

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.

# Properties

cssText: of type DOMString
  The parsable textual representation of the rule. This reflects the current state of the rule and not its initial value.
parentRule: of type CSSRule, readonly
  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 None.
parentStyleSheet: of type CSSStyleSheet, readonly
  The style sheet that contains this rule.
type: of type unsigned short, readonly
  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.

## cssutils only

seq:
  contains sequence of parts of the rule including comments but excluding @KEYWORD and braces
typeString: string
  A string name of the type of this rule, e.g. 'STYLE_RULE'. Mainly useful for debugging
valid:
  if this rule is valid

### __init__(self, readonly=False) (Constructor) | source code
x.__init__(...) initializes x; see x.__class__.__doc__ for signature Overrides: object.__init__ (inherited documentation)

### _setCssText(self, cssText) | source code
DOMException on setting 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: (self) Raised if the rule is readonly.

  ### _typestrings Value:
      ['UNKNOWN_RULE',
       'STYLE_RULE',
       'CHARSET_RULE',
       'IMPORT_RULE',
       'MEDIA_RULE',
       'FONT_FACE_RULE',
       'PAGE_RULE',
       'NAMESPACE_RULE',
      ...

  ### type The type of this rule, as defined by a CSSRule type constant. Overwritten in derived classes. 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. (Casting not for this Python implementation I guess...) Value:
      0
