The document discusses theming in Drupal, including an overview of templates, preprocessors, and base themes. It provides examples of using templates like page.tpl.php and preprocess functions to modify variables. Advice is given on tools that can help with theming like using base themes like Zen for rapid development and flexible layouts.

- 21. Benefits of BaseThemes • You don’t have to build everything yourself. Copy, override, and modify only what you need to. • Bug fixes. Others can fix any bugs in the base theme. • New features. For contrib Themes, there will occasionally be new features. • Support. If you have modified an existing theme, sometimes the only answer you will get to your support question is “Well, it works fine in the original theme.” • Rapid Theme Development. Many things are built for you.

- 26. Brief overview ofZen’s Layout method • Source-ordered HTML: The importance of the pieces of content determines the order in HTML, and not the graphic design. • Flexible layout options: • Fluid (100% width) or fixed-width layout • Optional horizontal navbar • 1-3 columns built-in. More columns are possible without mind-bending contortions. • Zen’s default Layout Method is completely pluggable. If you don’t like it, just replace the layout.css file with your own layout method: YUI, YAML, Jello Mold, Holy Grail, etc.
