The Experimental Full Screen Template is indeed a bit hard to work with.
Here’s a link to a video of me adding a background image with the Experimental Full Screen template and later trying to do the same with css.
Downsides to Experimental Full screen Template
- Only 1 image is allowed.
- The fact that you need to install a template, instead of it being available right away.
- Not intuitive.
As you know, our team is focused on Bloom training, and the more things in Bloom are intuitive the better. We would like to see a way of adding a background image via a menu, similar to the Comic Tool. In that tool you would simply browse for a background image and done.
I think that a lot of teams would really appreciate this feature.
