How do I remove the header on mobile sites, but keep the hamburger menu?

On the mobile version of my site, there is a white banner at the top, my logo is also white so it is not visible, and I do not want a coloured menu, I want the menu to be invisible essentially so that the banner photo for the page is the menu background also.

Yes. You can solve this. However can you share link to your site? We can check easier.
