improvements
============

Validation
----------
:prio: 1

CSS2.1 and CSS3 properties should be added completely and validation has to be redefined.
Possibility to add custom validation and register new properties?

CSS3 color module
-----------------
:prio: 1

implement rgba()

- named colors::

    Black = #000000         Green = #008000
    Silver = #C0C0C0        Lime = #00FF00
    Gray = #808080      Olive = #808000
    White = #FFFFFF         Yellow = #FFFF00
    Maroon = #800000        Navy = #000080
    Red = #FF0000       Blue = #0000FF
    Purple = #800080        Teal = #008080
    Fuchsia = #FF00FF       Aqua = #00FFFF

- "transparent"
- rgba(R, G, B, opacity): opacity in range (0,1)
- hsl(), hsla() ?
- SVG colors?
- "currentColor"
- System Colors are DEPRECATED!
- "flavor"?


Selector
--------
:prio: 1

- CSS2XPath converter -> use lxml.cssselector
- optimize selector parsing?
- **add query functionality**
    + specificity DONE
    + cascade


test improvements
-----------------
:prio: 1

- Token.EOF handle in all classes for end of stylesheet

    User agents must close all open constructs (for example: blocks, parentheses, brackets, rules, strings, and comments) at the end of the style sheet.

- line/col reporting tests
- tests with almost all details with comments
- check escape handling::

    \\@a \\{ \\: : \\; ; \\} }
    .\1 is valid selector

- csshack tests, see online tables (comment hack?)
- test tigris.css
- implement testsuite on HTML? http://www.w3.org/Style/CSS/Test/CSS3/Selectors/current/xhtml/index.html

- CSSStyleSheet.setSerializer()
- CSSStyleSheet.setSerializerPref()



CSSValue
--------
:prio: 3

**this feature may be implemented later as CSSOM defines the complete thing differently**

implement RGBColor, Rect and Counter

serializer
~~~~~~~~~~
- add preference option how color values should be serializer:

  ser.prefs.COLORS_HEX, also the DEFAULT?
        e.g. #123, so short form is possible
        ignored for rgba()
  ser.prefs.COLORS_HEXFULL
        e.g. #112233, so always 6digit hex
        ignored for rgba()
  ser.prefs.COLORS_RGB_INTEGER
        e.g. rgb(1.1, 55, 255), so range from 0-255
        also for rgba()
  ser.prefs.COLORS_RGB_PERCENTAGE
        e.g. rgb(10%, 20%, 100%), so range from 0 to 100%
        also for rgba()
  ser.prefs.COLORS_FROM_SOURCE
        use colors as used in CSS Source

  additionally:
    ser.prefs.NAMED_COLORS
        e.g. white for #fff or rgb(100%, 100%, 100%)

- **refactor**: all preferences values should be constansts like above

CSS2Properties
--------------
:prio: 3

needs to be implemented fully, setting of margin: 1px sets actually marginTop, marginLeft etc


performance
-----------
:prio: 3

- profile.py


serializer
----------
:prio: 2

- prettyprint convinience serializer?
- XML serializer to be able to handle CSS with XSLT, schemas etc?
- different coding styles?

Properties
----------
:prio: 3

Set styledeclaration properties with list of tuples? (dict done in 0.9.5)


LinkStyle, DocumentStyle
------------------------
:prio: 3

::

    // Introduced in DOM Level 2:
    interface LinkStyle {
      readonly attribute StyleSheet       sheet;
    };
    // Introduced in DOM Level 2:
    interface DocumentStyle {
      readonly attribute StyleSheetList   styleSheets;
    };
