General help

I was wondering if it's possible to embed a HTML5 interactive app into a moodle page and moodle book. The only way I've found to sort of get this working so to link from the moodle book/page to where the interactive is embedded. I was hoping someone may know a way to have the interactive display alongside the moodle book/page content.

I know how to do this [1] but it only embeds the content on a page by itself.
