The CSSStyleSheet interface represents a CSS style sheet.

# Properties

## CSSOM

cssRules
  of type CSSRuleList, (DOM readonly)
encoding
  reflects the encoding of an @charset rule or 'utf-8' (default) if set to `None`
ownerRule
  of type CSSRule, readonly. If this sheet is imported this is a ref to the @import rule that imports it.

Inherits properties from stylesheet.StyleSheet

## cssutils

cssText: string
  a textual representation of the stylesheet
namespaces
  reflects set @namespace rules of this rule. A dict of {prefix: namespaceURI} mapping.

# Format

stylesheet
  : [ CHARSET_SYM S* STRING S* ';' ]?
    [S|CDO|CDC]* [ import [S|CDO|CDC]* ]* [ namespace [S|CDO|CDC]* ]* # according to @namespace WD [ [ ruleset | media | page ] [S|CDO|CDC]* ]*

Method Details | [hide private]

### __init__(self, href=None, media=None, title=`u'````'`, disabled=None, ownerNode=None, parentStyleSheet=None, readonly=False, ownerRule=None) (Constructor) | source code
init parameters are the same as for stylesheets.StyleSheet Overrides: object.__init__

### _setCssText(self, cssText) | source code
(cssutils) Parses `cssText` and overwrites the whole stylesheet. Parameters: `cssText` - a parseable string or a tuple of (cssText, dict-of-namespaces) Raises: `NAMESPACE_ERR` - If a namespace prefix is found which is not declared. `NO_MODIFICATION_ALLOWED_ERR` - (self) Raised if the rule is readonly. `SYNTAX_ERR` - Raised if the specified CSS string value has a syntax error and is unparsable.

### _setCssTextWithEncodingOverride(self, cssText, encodingOverride=None) | source code
Set cssText but use __encodingOverride to overwrite detected encoding. This is only used by @import during setting of cssText. In all other cases __encodingOverride is None

### _setEncoding(self, encoding) | source code
sets encoding of charset rule if present or inserts new charsetrule with given encoding. If encoding if None removes charsetrule if present.

### add(self, rule) | source code
Adds rule to stylesheet at appropriate position. Same as `sheet.insertRule(rule, inOrder=True)`.

### deleteRule(self, index) | source code
Used to delete a rule from the style sheet. Parameters: `index` - of the rule to remove in the StyleSheet's rule list. For an index < 0 no INDEX_SIZE_ERR is raised but rules for normal Python lists are used. E.g. `deleteRule(-1)` removes the last rule in cssRules. Raises: `INDEX_SIZE_ERR` - (self) Raised if the specified index does not correspond to a rule in the style sheet's rule list. `NAMESPACE_ERR` - (self) Raised if removing this rule would result in an invalid StyleSheet `NO_MODIFICATION_ALLOWED_ERR` - (self) Raised if this style sheet is readonly.

### insertRule(self, rule, index=None, inOrder=False, _clean=True) | source code
Used to insert a new rule into the style sheet. The new rule now becomes part of the cascade. Parameters: `rule` - a parsable DOMString, in cssutils also a CSSRule or a CSSRuleList `index` - of the rule before the new rule will be inserted. If the specified index is equal to the length of the StyleSheet's rule collection, the rule will be added to the end of the style sheet. If index is not given or None rule will be appended to rule list. `inOrder` - if True the rule will be put to a proper location while ignoring index but without raising HIERARCHY_REQUEST_ERR. The resulting index is returned nevertheless Returns: the index within the stylesheet's rule collection Raises: `HIERARCHY_REQUEST_ERR` - (self) 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 style sheet is readonly. `SYNTAX_ERR` - (rule) Raised if the specified rule has a syntax error and is unparsable.

### replaceUrls(*args, **kwargs) | source code
EXPERIMENTAL Utility method to replace all `url(urlstring)` values in `CSSImportRules` and `CSSStyleDeclaration` objects (properties). `replacer` must be a function which is called with a single argument `urlstring` which is the current value of url() excluding `url(` and `)`. It still may have surrounding single or double quotes though. Decorators: `@Deprecated('Use cssutils.replaceUrls(sheet, replacer) instead.')`

### setSerializerPref(self, pref, value) | source code
Sets Preference of CSSSerializer used for output of this stylesheet. See cssutils.serialize.Preferences for possible preferences to be set.

### __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)

  ### cssText Get Method: _getCssText(self) Set Method: _setCssText(self, cssText) - (cssutils) Parses `cssText` and overwrites the whole stylesheet. Delete Method:
      '(cssutils) a textual representation of the stylesheet'

  ### encoding return encoding if @charset rule if given or default of 'utf-8' Get Method: _getEncoding(self) - return encoding if @charset rule if given or default of 'utf-8' Set Method: _setEncoding(self, encoding) - sets encoding of charset rule if present or inserts new charsetrule with given encoding. Delete Method:
      '(cssutils) reflects the encoding of an @charset rule or \'UTF-8\' (de
      fault) if set to ``None``'

### namespaces Namespaces used in this CSSStyleSheet. Get Method: unreachable(self)

### ownerRule (DOM attribute) NOT IMPLEMENTED YET Get Method: unreachable(self)
