Does anyone know how to move the hamburger menu in mobile to the top left corner? I'm sure it's something to edit within the header and sidebar but I don't know enough coding to figure it out.
Please share your site url.
So that i can check and provide you exact solution here.
For that you have to do customization in header.liquid files.It is not possible by css only.
Very strange of them do decide to fill such a big portion of the mobile screen with a menu button - in the middle of the screen!
