Dear Jonas @jonasschulte
Great to hear you came to a solution, using the z-index is a good way to do it :)
Of course things may change in the future but due to your code's simplicity i don't think it will be an issue.
Do you need the additional css thats not z-index, so just:
.sitetitle { z-index: 0; }Just curious but doesn't matter at all! just a thought :)
Best wishes Jonas and have a wonderful day!
Richard
