A great theme for beginner designers looking to master the dark arts of theming. This design, created by Betty Biesenthal of www.design-house.ca, features a three column layout ideal for simple Web sites. This theme uses the NineSixty base theme for its layout.
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.
Really important note: December 2011
Responsive layout support has now been committed to a Drupal 7 branch of Fusion. Individual layouts (e.g. tablet landscape vs smartphone) will be able to be toggled on/off on a per-subtheme basis, and most functionality of Fusion Mobile is already covered in this branch. Thus, this project for Drupal 7 will no longer be supported, instead recommending the responsive option in Fusion itself.
