A Python package to parse and build CSS Cascading Style Sheets.

Based upon and partly implements the following specifications (DOM only, not any rendering facilities):

DOM Level 2 Style CSS
  DOM for package css
DOM Level 2 Style Stylesheets
  DOM for package stylesheets
CSSOM
  A few details (mainly the NamespaceRule DOM) is taken from here. Plan is to move implementation to the stuff defined here which is newer but still no REC so might change in the future
CSS 2.1
  Rules and properties are defined here
CSS 2.1 Errata
  A few erratas, mainly the definition of CHARSET_SYM tokens
MediaQueries
  MediaQueries are part of `stylesheets.MediaList` since v0.9.4, used in @import and @media rules.
Namespaces
  Added in v0.9.1 and updated to definition in CSSOM in v0.9.4
Selectors
  The selector syntax defined here (and not in CSS 2.1) should be parsable with cssutils (should mind though ;) )

Please visit http://cthedot.de/cssutils/ for full details and updates.

Tested with Python 2.5 on Windows XP.

This library is optimized for usage of `from cssutils import *` which import subpackages `css` and `stylesheets`, CSSParser and CSSSerializer classes only.

Usage may be:

    >>> from cssutils import *
    >>> parser = CSSParser()
    >>> sheet = parser.parseString(u'a { color: red}')
    >>> print sheet.cssText
