When triggered, the mobile header’s height is way too large and it overlaps the underlying element (screenshot). As I have a background-color set, the underlying element even becomes invisible.
Where should I change this (and what should I change)?
I have tried everything, but the mobile header remains an issue.
in Customizer > Typography edit the Primary Navigation Menu items, and in mobile view check the Line Height, i think it is set to 18 without a unit, change it to something like 50px for mobile.
