Help with adding a gradient animation to a specific section

Hey,

I've been trying to add a gradient background animation to a specific section of my Squarespace site. I've tried different variations of code that I found in forums but nothing seems to be working.

I'm specifically looking to add the animated background to the first section of my home page. 'Purpose meets play section'

using the colour code: 

#F28F00 #E9600B #D93175 #F28F00

This is my site: https://www.nubicollective.com/

Any assistance would be greatly appreciated, thank you!

Yes! It works great
