HTML block

From MoodleDocs

An HTML block is a standard block used to add text, multimedia, widgets etc to a site front page or course page. The title bar may be left blank if desired.

Overview of HTML block

Two HTML blocks from https://learn.moodle.net

The block is flexible and can incorporate a variety of functions and uses in the content area. It has the standard Moodle Text editor for formatting text, adding images or creating links, switching to code view and allows any valid HTML mark-up to be used. This enables embedding video, sounds and other files which can add unique elements to a course or site page.

Site administration settings

To aid with styling the block, an administrator can, from Administration > Site administration > Plugins > Blocks > HTML, toggle the ability to allow additional CSS classes to be set in individual block instances. If it is enabled, a field appears at the bottom of HTML block instance's configuration forms:


Please note that if additional CSS classes have been added and the administration setting is then disabled, the form settings are saved in the database and will reappear if this is re-enabled.
