Hi there.
We've just upgraded to Moodle 3.3.1, and in part due to issues we're having with the Essential theme after the upgrade, we're trying to work with the Boost theme (build 2017051500 is what is indicated in Plugins Overview).
With the Essential theme, we had a wide institutional banner, as well as slider, featured on our home page.
If possible, I'd like a bit of help with reproducing this with the Boost theme. I'm attaching the custom CSS we used previously with the Essential theme.
thanks for any help you can provide!
Jacques
