I tried that of course, but apparently couldn't find the right html.
Now it works so far.
My problem now is that I would like the display to be as in default.
I can stand on my head, I can't do it with the surfaces.
I tried it in the css. I exchanged the complete html content for testing so that I can see where I can do something.
All to no avail :-(
Can someone please tell me where I have to do something to make it look like the picture with the arrows?
