Issues with designing mobile version, duplicating pages and the desktop layout

I’m almost finished with my portfolio site, but I noticed there’s white space when I scroll the page to the left: https://cl.ly/65236562d650. I’m also running into a couple of other issues:

How to reuse my pages as a template so I don’t have to build new pages from scratch again?
How can I fix the mobile version without affecting the desktop version?

Thanks!

Hi @cbass,

The white space on the right is probably the cause of width:100vw on elements with no max-width (as explained here)
Try giving all these element max-width:100%

You can copy paste any element inside your pages (if you put everything in one div it is like copying the hole page)

And regarding mobile versions, start here:
