Thanks! now it works. But the color only affects to the active panel. Is it possible the color affects to general, “inactive” panel too?
I’ve added this code into my custom css box, but didn’t worked…
If it’s necessary, I can give you my credentials.
Thanks for your reply.
Well, then I think I prefer change the design, and use other element instead of that grid.
