Hi!

My knowledge of code is quite limited, but what might be helpful is to check out existing CodePens. For example this one with an animated button which is triggered on hover: https://codepen.io/Gingernaut/pen/qOgMLy

This article might answer some questions about how to use the animation as a background: https://medium.com/stink-studios/having-fun-with-lottie-web-and-bodymovin-1b9042b97252

Hope it helps!
