now that my menu background color issue is resolved, I am fiddling around with my pages. I want to attach custom Header Pictures to each page and since this ist not possible via the Header customizer I created an extra row on the page, put in site origin Picture widget and uploaded a Header Image with the size 1920x400 px. And on the Desktop PC, it Looks great:
however, on mobile, there are some issues.
iPad: upper section of the Picture is absorbed by the menu, it always gets “sucked” up.
iphone: Image is very small and has White beams on the left and on the right side.
Is there a fix to this?
