Navigation menu cuts off on right side on mobile view

That worked to restrict the size of the container, and it looks right in Webflow…

But on my phone it cuts off on the right side.

Is that because I have overflow set to hidden, but maybe the body itself is too wide so it’s aligning with the actual size of the body? There’s a video element that extends past the horizontal borders, but I used overflow settings to get rid of the scroll bar.

Thinking that, I changed fit from cover to contain, but again no difference. And that wouldn’t explain why it looks correct on Webflow but not my phone, right?
