still looking for a way to remove the header (not the menu or logo) on mobile…the code you provided above left the header but elimintated the menu and the logo..the opposite of what i am looking for…please assist, and the update to 4.1.8 seemed not to have solved the unresponsive header problem (your theme template says it has to be 2560 x 400, which is what I created and uploaded to the header section of customizer.
thank you
