I'm a beginner on CSS and HTML, and I have to fix a problem on this website: https://arena-supplements.com/ on the Mobile Version, when you scroll left, you still see a lot of space outside the page.
The problem seems to be the sticky header or this "go to top" button in the footer, but I have no other idea how to fix it.
Would a max-width solve this?
Try this to add in media query
body, html{overflow-x:hidden;}
