Change the background

Site URL: https://dachshund-wolf-mdy7.squarespace.com/

Hello I created the above page and tried to ad a css code for gradient animated background from here

https://www.marksmen.studio/blog/animated-gradient-backgrounds-in-squarespace

This the code I added to t addition tab of the page

"<style>
#collection-626bc772534e5c386dbcaf1c
{ background: linear-gradient(270deg, #e32121, #2004e3);
background-size: 200% 200%;
-webkit-animation: AnimationName 10s cubic-bezier (0.68, 0.55, 0.265, 1) infinite;
-moz-animation: AnimationName 10s cubic-bezier (0.68, 0.55, 0.265, 1) infinite;
animation: AnimationName  10s cubic-bezier (0.68, 0.55, 0.265, 1) infinite;}

</style>

"

Th gradient color appears on begging  but then is back again.

Do I have to do something else?

Thanks.
