## Background

The Symbian mobile phone supports customizing backgrounds in themes. The background of a theme in Carbide.ui consists of two different component options:

### Active Background

This is the active background screen of the mobile phone. Most of the screens contain an active background.

### Idle Background

This is the idle background screen of the mobile phone. This is the background screen for, for example, the screen that is displayed when mobile phone's keys are locked and the screen saver is not yet active.
Note: In Carbide.ui, you can animate the background.
Figure: Default and Customized Active Background
Note: When you edit the active background component, all the screens that contain an active background are affected. If you do not set an idle background, the active background component is displayed as the idle background also.
