YouTube Video Background

Posted by vs0068169 Apr 2, 2018

For those that want to add a bit more jazz to some special courses you can add a dynamic background by embedding a video behind the page. The screen grabs above based on code I found on the web ages ago here: FullScreen YouTube Video Background In Pure CSS  and then modified here: 


..and then turned it into a plugin here: Moodle plugins directory: Youtube_Page_background


We don't have access to that plugin suite but we can do it manually. If you paste the code into a label and then save it you can have a dynamic and ever-changing background (with audio).


It works best in "Clean" or "More" as you can scroll down and go full video (See pic RHS above). It work fine in "Boost" but you can't scroll.


I've used it for online chill-out rooms (waterfall) , self promotion (a Moodlemoot presentation), and to annoy my coworkers/students. Hope this is useful to someone.
