Fusion

Fusion is a powerful base theme, with layout and style configuration options built in that you can control through Drupal's UI. It's based on a simplified 960px or fluid 12/16-column grid with options for responsive layouts for mobile devices. It's designed to be used with the Fusion Accelerator module (or with Skinr in Drupal 6), with numerous useful block styles included.
Fusion Mobile is a Fusion Core subtheme designed for creating a custom theme targeting mobile devices. By using a separate subtheme, you can control your theme settings and block layout/contents specifically for mobile devices.
