The CSSAnimation interface of the Web Animations API represents an Animation object.

This interface inherits properties from its parent, Animation.

CSSAnimation.animationName Read only

Returns the animation name as a string.

This interface inherits methods from its parent, Animation.

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();
console.log(animations[0]);
