Drupal provides a few themes with the core installation and other contributed themes are available for download from Drupal, many of which are included with this distribution.

Under themes in the administration area, administrators can choose which themes to enable and designate the default theme for the site. If multiple themes are enabled, users will be able to choose their default them in their account section.

The themes section also offers various configuration options which affect the display and navigation for the site. Administrators can select these globally for all themes, or customize them on a per theme basis. For example, the global settings page contains the following options:

• Logo image settings. Used to override the default logo for a particular site theme.
• Menu settings. The primary links and secondary links fields here are for customizing the navigation links available in the header of every page. Note that if the primary links field is left blank, Drupal will automatically generate links to enabled modules. Some of the themes offered on this site use a specified format for the creation of primary and secondary links. Thus, in configuring any themes, always view both the global theme settings and the one's for the individual theme you are using.
• Display post information on. Controls whether the submitted by and date information is displayed for a given node type.
• Toggle display. Enables or disables various page elements.

NOTE: Some Drupal themes are intended to be 2 column; others 3 column or 2. Some are fixed width; some flexible. Some work better in some older browsers than others. Thus, be sure to check each theme that you enable for your users to make certain that it is displaying correctly.
