Help Needed With Parallax Effect

Hello, Guys

I have been at the forum for a quite a while, been posting questions and gotten some really good answers, but unfortunately, I’m getting stuck at one major problem, which is parallax effect.

My design is this!

There are multiple colorful bold lines all over the page which needs to be parallax. I think I figured how to do it but then the problem came on different sizes of the devices.

Example attached here —>

Here’s the read-only link!

Please if anyone can fix this.
