Pressbooks supports several different kinds of media and interactive content.
To embed approved content, all you need to do is drop the URL of the video, audio or other element (not the embed code with iframe tags wrapping it) directly into the visual editor, and Pressbooks will automagically change the URL to an embed.
The full list of approved content is too long to include here, but includes major providers such as:
- Social media (Twitter, Instagram, Facebook etc.)
