1) The sides (yellow arrow) surrounding the navbar, how do I change that to "primarydarker"? I was able to change the background by Style Properties: General. I can't seem where to change the side areas however. Template? If so, which and where?
2) The navbar area. I would assume this is a fairly common question, but I didn't find anything in the search here (perhaps I used the wrong terms). How do I change the primary and secondary area in the navbar (marked by the red arrows).
Also, is there a "map" of things to change and where to find them? Or is the best way right now to try to experiment and explore?
Thanks in advance for the help.
