The preview area extends beyond the screen

Hi all fellow webflow users and experts.

I really need help with my current project.
I work on templates purchased by my clients. After quite a lot of editing, finally everything is ok. But in the mobile version, there is an empty area on the right screen that makes whole layout scrollable to the right.

Preview is attached.
Can someone please help me.
Thank you so much in advance.

Did you tried overflow: hidden on the page-wrapper or main-wrapper?

Hi, thanks for the reply.
I have apply hidden overflow on the main wrapper. But I think it doesn’t work.
