The Administration Theme
Administration forms tend to be wide and long, sometimes not fitting too well within the confines of the
content area defined for a given theme. To address this problem, Drupal 8 lets you specify a theme that
should be used for administrative functions. You can try your new theme to see if it works for administration
screens, or you can pick a different theme to use whenever a site administrator is performing site
administration tasks. Typically, a simple clean theme that is at least 960px wide works best as the admin
theme. To change the administration theme, simply click the Appearance menu item at the top of the page
and scroll to the bottom. You’ll see a section titled Administration Theme. From the list of themes in the
drop-down list, select a theme that you know will work with administration forms. By default Drupal 8
enables Seven as the administration theme, because it accommodates administration screens. You may also
change the administration theme to any other theme listed in the drop-down list. If you change the value,
make sure you click the “Save configuration” button.
Configuration Options
Drupal 8 provides a set of configuration options that, when changed, updates certain aspects of what is
displayed within your theme. Depending on whether the theme author adhered to Drupal standards, you
can use this form to determine which elements are displayed on the page (Logo, Site Name, Site Slogan, and
so on), whether the theme should use its default logo, and whether the shortcut icon should be used (the
shortcut icon is also known as the favicon; it’s the little logo that appears to the left of your browsers address
bar). To get to this screen, simply click the Appearance menu item in the top menu and click the Settings tab
at the top of the Appearance page. See Figure 6-9.
