Standard themes

Theme selector

An administrator can set a theme for the site in Administration > Site administration > Appearance > Themes > Theme selector.

Different themes may be set according to 'device type' - default, legacy (for older browsers), mobile and tablet.

Go to Administration > Site administration > Appearance > Themes > Theme selector

Click on the "Select theme" button next to the type you wish to change
Scroll down to see the previews of the available themes and click on the "Use theme" button to chose the theme
The next screen will provide information about the theme. Click "Continue"

Note 1: Moodle caches themes so if you don't immediately see changed settings that you were expecting, click the "Clear theme caches" button at the top of the Theme selector page.

Note 2: The selected theme may be overridden if user/course or category themes have been allowed in the Theme settings.

Tip: The MyMobile theme is especially designed for mobile devices.
