Hello,
Are the header and footer on tablet devices the same as the layout for mobile or desktop?
The footer is the same, it could just be changed to the view as configured in the page builder or via Theme Settings.
The header depends on the breakpoints, if the breakpoints of the laptop/desktop, the desktop header is shown, if not, the mobile header is shown.
And if I want to design a separate header for tablets, what is the solution?
Sorry to say, but right now there is no option in Theme Settings available to achieve that. It requires Customization and this is beyond our limitations and support policy scope. Hope you can understand our limitations.
Kind Regards
