How to achieve a 'contained scroll' or 'framed scroll'. See example.

Site URL: https://brandsbyavid.com/case-study/we-are-warriors/

Hi everyone,

I'm trying to replicate the MacBook visual on this site: https://brandsbyavid.com/case-study/we-are-warriors/
(scroll to the bottom). The MacBook remains stationary and the contents within scrolls.

I want to use this technique to showcase web designs.
There is not a built in effect on Squarespace, any advice?

I hope someone can help!
Thanks,

Tom
