Icons not working

Question

I'm working with a gooey menu from codepen trying to learn how it works and such but hey it's not.
It's supposed to look like this: https://codepen.io/lbebber/pen/LELBEo

Right now it looks like this: https://code.sololearn.com/W13v1Y77Qgdn/#html

I had to turn the SCSS into CSS because SL doesn't support it. I want to work with it but I need it to not be broken first. Anyone know what's wrong?

Answer 1

//It seems there is still some SCSS left after css line 100
