Watershed theme, including base theme and sub-themes
Introduction to the Watershed Theme
The Watershed theme is based upon the Basic theme by Rain City Studios. See: http://drupal.org/project/basic See: the diagram of the page elements and region layout that ships with this theme (watershed_theme_diagram.png)
Watershed "Child" Themes
The Watershed theme should not be used on it's own, but rather as the parent theme of one or more child themes that ship with it, or are created by other designers/developers. You cannot use any of these child themes w/o installing the parent Watershed theme, as child theme inherit code, layout, stylesheets, etc., from the parent theme.
To learn more about working with theme inheritance, see: http://drupal.org/node/225125.
Changing the Layout
The layout used in Basic (and thus used in the Watershed theme) is fairly similar to the Holy Grail method. It has been tested on all major browser including IE (5>8), Opera, Firefox, Safari, Chrome ...
The purpose of this method is to have a minimal markup for an ideal display. For accessibility and search engine optimization, the best order to display a page is ] the following :
1. header
2. content
3. sidebars
4. footer
This is how the page template is buit in basic, and it works in fluid and fixed layout. Refers to the notes in layout.css to see how to modify the layout.
