No, You need to set the animation for every aspect of the page, although its very simple, I can send the full CSS if you'd like! Do you have discord?
Yes i got a discord, but was more interested on how you get access to do it as i was doing research on seting up a nice itch.io page
you just email itch support asking for access, and they should give it to you!
