Genesis is an standards compliant, accessible and semantically rich starter theme for Drupal. Genesis is easy to theme yet extremely flexible, giving you endless theming possibilities. Genesis makes building a standards compliant accessible theme easier than starting from scratch.
Gensis validates XHTML Strict, CSS3 and is WCAG AAA and WAVE compliant.
Genesis now includes three starter subthemes; genesis_SUBTHEME, genesis_ULTRALITE and genesis_DARK.
The DARK starter subtheme adds support for dark style themes, includes fully styled admin, tables, forms etc and supports Views, Panels and Vertical tabs. View screenshots.
Genesis employs the top-down approach. The idea is to start with too much, add even more, and then prune what you don't need. This is similar to Views, CCK, Panels and many other Drupal projects—ultimately this approach offers endless theme potential without compromise. Firebug will speed up your development process and help you understand how the CSS works and how you can modify it. The Genesis modular stylesheets include many CSS selectors—these show up in Firebug where you can quickly add properties and prototype styles.
