Sahana Eden supports custom Themes as part of it's overall [DeveloperGuidelines/Templates Templates] system.

This allows customisation of:
* Layout
* CSS

NOTE: This is still a work-in-progress: not everything here is ready yet & the details may change!

=== Default Theme ===
By default these files are used:
* {{{/private/templates/default/views/layout.html}}}
* {{{/private/templates/default/views/load.html}}}
in non-Debug mode:
* {{{/static/themes/default/css/sahana.min.css}}}
in Debug mode:
* {{{/private/templates/default/css.cfg}}}
* {{{/static/themes/default/css/layout.css}}}
* {{{/static/themes/default/reset.css}}}
* {{{/static/themes/default/layout.css}}}
* {{{/static/themes/default/shortcut.css}}}
* {{{/static/themes/default/widgets.css}}}
* {{{/static/themes/default/style.css}}}
* {{{/static/themes/default/homepage.css}}}
etc

=== User Theme ===
A new Theme should match the name of the controlling Template.

To create a new theme:
1. Specify the Theme name in your template's {{{/private/templates/<templatename>/config.py}}}:
 * {{{settings.base.theme = "themename"}}}
1. Create new folders to hold the theme elements:
 * {{{/static/themes/<themename>/css}}} which will usually contain these files: {{{layout.css}}}, {{{style.css}}} (it is normally assumed that {{{/static/themes/default/css/widgets.css}}} is also used)
 * {{{/static/themes/<themename>/img}}}
1. If not already using a template create one: {{{/private/templates/<templatename>}}}
1. Create these files in your templates folder:
 * {{{/private/templates/<templatename>/__init__.py}}} - this can be empty but must be present.
 * {{{/private/templates/<templatename>/css.cfg}}} - list of CSS files to use in Debug mode, or be compressed together for the normal non-debug mode by the Build script ({{{static/scripts/tools/build.sahana.py}}}) into:
  * {{{/static/themes/<themename>/css/sahana.min.css}}}
 * {{{/private/templates/<templatename>/views/layout.html}}} - overall layout of the HTML.

NB Production sites who wish to compile their code either need to hardcode the theme name in their {{{views/layout.html}}} or upgrade to Web2Py version: 2.00.0 (2012-06-17 23:36:32) or newer

==== Ext Theme ====
Use [http://www.codebeautifier.com CodeBeautifier] to merge the {{{ext-all-notheme.css}}} with {{{xtheme-gray.css}}} (merges properties on the same selectors which most minifiers don't):
 * {{{static/scripts/ext/resources/css/ext-theme.min.css}}}
Can also use this to merge a custom theme, e.g. built with http://extbuilder.dynalias.com
