The issue with height is due to the larger height of the logo. If upload image with height around 60px, the height of the header should be fine. Or simply add following code inside Appearance > Customize > Additional CSS :
The code works great for logo height. but still the header height is still big and i want the humburg icon to be on top right corner on mobile view.
One more issue that search icon is not visible on mobile.
