The animation in the following example is defined in CSS with the name slide-in. Calling Element.getAnimations() returns an array of all Animation objects. In our case this returns a CSSAnimation object, representing the animation created in CSS.

.animate {
  animation: slide-in 0.7s both;

@keyframes slide-in {
  0% {
    transform: translateY(-1000px);
  100% {
    transform: translateY(0);
let animations = document.querySelector(".animate").getAnimations();
