  20. 20. Base Themes Powerful Frameworks for Beginners and Power Users
  21. 21. Benefits of Base Themes • 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. 26. Brief overview of Zen’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.
