Applies to: Moodle 3.2
Themes may only be installed by Moodle developers after careful testing. Most third-party themes do not work well because of the following issues:
Designers can embed unit-specific images into individual course pages as labels or blocks to emulate a theme without necessitating changes in code.
Custom banner theme development is available for large University units such as coordinate campuses or schools. Contact Moodle Support for more information.
Note: If a custom banner theme is not compatible with the next Moodle version, sites must be converted to the standard banner theme until the new custom banner theme is developed.
