This task is performed by users with System Administrator privileges. Styles add color and depth to a site. When multiple sites are used, they can be utilized to aid users in differentiating which site is being used by applying a different style setting to each site.
To add a style in System Administration:
Select Admin > Configuration > Style > Styles in the Navigation pane; the Styles page displays.
Enter a value in the DESCRIPTION field.
NOTE: The value entered represents the color and appearance the pages will have once the style is applied. Enter a name that describes the color and appearance of the style.
