HTML & CSS animation not working when added to website

I have a animation made in HTML & CSS on codepen.io, here’s the animation – https://codepen.io/akshzyx/pen/OJOqpav.

It works fine on codepen but when tried to used in personal website, animations stop working.

Eyes blinking is the only thing that works on website. Tried in 2-3 browsers, same everywhere.

How can I fix this?
