Changing an assignable unit's background properties

The default background color, the default background image, and the default background sound are inherited from the project properties by default. Changes applied to the background color, image, or sound within your assignable unit's properties will only be applied to the pages contained within the assignable unit.

To change these background properties:

1. Double-click the assignable unit graphic of the assignable unit you want to change in the Project Explorer.

   The Assignable Unit Properties window opens.

2. Click the Background tab.

3. Specify the following background information:

   Default Background Color	The default background color inherited from the project properties is specified. Use the list to select a new default background color. Select a predefined color, select Inherit to use the inherited color, or select Custom to select a custom color from the Color palette. The custom color you select is saved to the Recent Colors list. If you choose a background image, you will not be able to see your background color. See also: Selecting custom colors
   Default Background Image	The default background image inherited from the project properties is specified. To use a new background image for the pages of your assignable unit, select a previously imported image from the list or click the Import button to navigate and select the image. You can also click the arrow within the Import button to choose from the following: From File Select this to navigate and select an image. Media Library Select this to launch your media library to select an image. See also: Organizing media Click Edit to modify the image if necessary. You can also use the Background Wizard to create a background for project. For details, see Creating custom backgrounds. Background images are tiled (repeated) by default. Background images that are the exact same size as the page (height and width) will not be tiled. If the background image size is different from the page size - either smaller or larger - it will be repeated both horizontally and vertically to cover the entire visible background area within the browser window. If you choose a background image, the background color will not be visible, unless the image is somewhere transparent.
   Default Background Sound	The default background sound inherited from the project properties is specified. To use a new background sound for the pages of your assignable unit, select a previously imported audio file from the list or click the Import button to navigate and select the audio file. You can also click the arrow within the Import button to choose from the following: From File Select this to navigate and select an image. Media Library Select this to launch your media library to select an image. See also: Organizing media The background sound is continuous; it does not restart as users navigate from one page to the next. The sound will continue playing and repeat until the user navigates out of the assignable unit or closes the project. A page with background sound and 24 or more media configured to automatically start might experience issues on mobile devices. For more information, see Automatically playing media on mobile devices.
