Parallax in 7.1 using sections overlapping rather than background

Hi !

I was wondering if there is a way to create overlapping section rather than background. Something similar to parallax effect but for entire section content not just its background.

For example, I want as I scroll down section 2 to cover section 1 (both background and text) rather than only covering the background.

Currently, I am using the parallax code from https://schwartz-edmisten.com/blog/how-to-add-parallax-to-squarespace-7-1

I really appreciate your help!
