CSS 3 Modules

Selectors 3

See cssselect can be used to parse selectors.

TODO: give an example of how to use it with tinycss.

.. module:: tinycss.color3

Color 3

This module implements parsing for the <color> values, as defined in CSS 3 Color.

The (deprecated) CSS2 system colors are not supported, but you can easily test for them if you want as they are simple IDENT tokens. For example:

if token.type == 'IDENT' and token.value == 'ButtonText':
    return ...

All other values types are supported:

• Basic, extended (X11) and transparent color keywords;
• 3-digit and 6-digit hexadecimal notations;
• rgb(), rgba(), hsl() and hsla() functional notations.
• currentColor

This module does not integrate with a parser class. Instead, it provides a function that can parse tokens as found in :attr:`.css21.Declaration.value`, for example.

.. autofunction:: parse_color

.. autofunction:: parse_color_string

.. autoclass:: RGBA

.. module:: tinycss.page3

Paged Media 3

.. autoclass:: CSSPage3Parser

.. autoclass:: MarginRule

Other CSS modules

To add support for new CSS syntax, see :ref:`extending`.
