Inspecting the returned CSSTransition

The transition in the following example changes the width of the box on hover. Calling Element.getAnimations() returns an array of all Animation objects. In our case this returns a CSSTransition object, representing the animation created.

css
.box {
  background-color: #165baa;
  color: white;
  width: 100px;
  height: 100px;
  transition: width 4s;
}

.box:hover {
  width: 200px;
}
js
const item = document.querySelector(".box");
item.addEventListener("transitionrun", () => {
  let animations = document.querySelector(".box").getAnimations();
  console.log(animations[0]);
});
