How do I add this codepen animation to my homepage

Site URL: https://www.joshwilldesign.co.uk

I'm trying to add a code block to my homepage using code from codepen (https://codepen.io/rscheuer/pen/jOLKyxG)

I've been unsuccessful so far, so much so that I added this code and my homepage became uneditable afterwards.

Anyone able to help?

Thank you in advance!
