Plugin provides an Panel for Gutenberg Inspector which allows you to animate Core-Blocks. (see screenshots below)
Tested in a WP 6.0 Not sure if this works with all core blocks. But with rather simple ones (like headlines) it should work no warranty
It comes with a JS and a CSS File for Frontend.
Animations are only shown in frontend not in the editor.
Ask me if you need the src files lars@larslo.de
Animation from here https://github.com/animate-css/animate.css
clone/download this repo. put it into wp-content/plugins and activate it.
