Great, I didn’t know that an image was shown, so this did the trick for me ??
I had to paste it outside all “trappers”, i.e. at the very bottom.
And then I tried to change the background color of the boxes in the same css entry but it seems like there is a darkifying layer over it, right? For example when I set backgroun-color: white !important; it becomes gray. Can one adjust that?
Many thanks!
