Objects implementing the CSSMediaRule interface can be identified by the MEDIA_RULE constant. On these objects the type attribute must return the value of that constant.

# Properties

  media block.
cssText: of type DOMString
  The parsable textual representation of this rule
media: of type stylesheets::MediaList, (DOM readonly)

Method Details | [hide private]

### __init__(self, mediaText=`'``all``'`, name=None, parentRule=None, parentStyleSheet=None, readonly=False) (Constructor) | source code
constructor Overrides: object.__init__

### _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. Parameters: `cssText` - a parseable string or a tuple of (cssText, dict-of-namespaces) Raises: `NAMESPACE_ERR` - (Selector) Raised if a specified selector uses an unknown namespace prefix. `SYNTAX_ERR` - (self, StyleDeclaration, etc) Raised if the specified CSS string value has a syntax error and is unparsable. `INVALID_MODIFICATION_ERR` - (self) Raised if the specified CSS string value represents a different type of rule than the current one. `HIERARCHY_REQUEST_ERR` - (CSSStylesheet) Raised if the rule cannot be inserted at this point in the style sheet. `NO_MODIFICATION_ALLOWED_ERR` - (CSSRule) Raised if the rule is readonly. Overrides: cssrule.CSSRule._setCssText

### deleteRule(self, index) | source code
index within the media block's rule collection of the rule to remove. Used to delete a rule from the media block. DOMExceptions INDEX_SIZE_ERR: (self) Raised if the specified index does not correspond to a rule in the media rule list. NO_MODIFICATION_ALLOWED_ERR: (self) Raised if this media rule is readonly.

### add(self, rule) | source code
Adds rule to end of this mediarule. Same as `.insertRule(rule)`.

### insertRule(self, rule, index=None) | source code
rule The parsable text representing the rule. For rule sets this contains both the selector and the style declaration. For at-rules, this specifies both the at-identifier and the rule content. cssutils also allows rule to be a valid CSSRule object index within the media block's rule collection of the rule before which to insert the specified rule. If the specified index is equal to the length of the media blocks's rule collection, the rule will be added to the end of the media block. If index is not given or None rule will be appended to rule list. Used to insert a new rule into the media block. DOMException on setting HIERARCHY_REQUEST_ERR: (no use case yet as no @charset or @import allowed)) Raised if the rule cannot be inserted at the specified index, e.g., if an @import rule is inserted after a standard rule set or other at-rule. INDEX_SIZE_ERR: (self) Raised if the specified index is not a valid insertion point. NO_MODIFICATION_ALLOWED_ERR: (self) Raised if this media rule is readonly. SYNTAX_ERR: (CSSStyleRule) Raised if the specified rule has a syntax error and is unparsable. returns the index within the media block's rule collection of the newly inserted rule.

### __repr__(self) (Representation operator) | source code
repr(x) Overrides: object.__repr__ (inherited documentation)

### __str__(self) (Informal representation operator) | source code
str(x) Overrides: object.__str__ (inherited documentation)

Property Details | [hide private]

### 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...) Get Method: unreachable(self)

### cssText (DOM attribute) The parsable textual representation. Get Method: _getCssText(self) - returns serialized property cssText Set Method: _setCssText(self, cssText) - DOMException on setting

### name An optional name for the media rules Get Method: unreachable(self) Set Method: _setName(self, name)

### media (DOM readonly) A list of media types for this rule of type MediaList Get Method: unreachable(self)

### wellformed READONLY Get Method: unreachable(self)
