Mobile header width issue

Site URL: https://www.inkblotastrology.com/

Hello! My 7.1 website is just one page (the home page) so I hid the mobile hamburger menu using some code. But the issue now is I think the hamburger is still technically there taking up space or something because the header is too wide for mobile now; the whole site doesn't stay centered because the header width is too long with my logo at the size it's at with the hidden hamburger menu. I attached a video to show what I mean.

This wouldn't be an issue if Squarespace allowed us to remove the mobile menu, but they don't yet, so it's gonna have to be code. Is there some kind of code that can help my mobile site stay put/centered without scrolling to the right? 

P.S. I tried finding code to make the hamburger smaller, but none of the code I found worked, or at least it didn't fix this specific problem.

Thank you!
