How can I add white space between sections on mobile only?

Site URL: https://bluebird-porcupine-yzdg.squarespace.com/home-copy-1

I would like to separate my sections on mobile by adding some white space between each section on mobile only (see image1)

If I add a blank section on mobile it's quite high (see image2).

Ideally, I would just like it like image 3.

Please help!
