I am trying to add some J query to my tribute page, and it wont work for me at all. I just want to make the title animated a little bit, and for some reason it’s registering it. Can someone help me out? thanks!

EDIT: after some more research, I had to add the the j query library called Animate.css by adding
Link tag:

CDN url: https://cdnjs.cloudflare.com/ajax/libs/animate.css/3.5.2/animate.min.css

Anyway - I am still somewhat confused on the different JS libraries and when to use them/how to use them. Could someone clear that up?
