Hi there! I'm in the middle of building my site, and at some point would like to make it so that every time you visit the homepage the background colour (of both index and exhibit) is a different (not totally random; more like 20 pre-selected ones). I'm only talking one colour at a time, but never the same as the previous
I've searched the forums a lot and haven't found anything which can help with exactly this. I'm very new to coding and such so I probably need everything explained to me very clearly.
My site: mutualdislike.com/
Thank you kindly.
