In this section, we will discuss how to [create](creating_basic_HTML_elements.md) and [embed](adding_HTML_elements.md) interactive HTML/Javascript elements created in HTML/JavaScript in a TeachBook. These HTML/Javascript element work very fluently and don't require a python kernel running in the background.

This could be for example interactive 3d figures:

Or other interactive graphs:
