Grey Container in Quiz

Hi there,

My second post is about a quiz container which is grey and crappy against the white background of the page. My Moodle host won't give me access to CSS and advises me that I can't change this. Does anyone here have a solution (image below).

Quiz with unnecessary grey container on a white page: https://drive.google.com/file/d/1myZGR0lObLU1Weq8y0cKVvhKe-Dw9kNG/view?u...

Thanks!

Charlie
