The animationend event is fired when a CSS Animation has completed. If the animation aborts before reaching completion, such as if the element is removed from the DOM or the animation is removed from the element, the animationend event is not fired.

The original target for this event is the Element that had the animation applied. You can listen for this event on the Window interface to handle it in the capture or bubbling phases. For full details on this event please see the page on HTMLElement: animationend.

This example listens for the animationend event:

window.addEventListener('animationend', () => {
  console.log('Animation ended');
});

The same, but using the onanimationend event handler property:

window.onanimationend = () => {
  console.log('Animation ended');
};

See a live example of this event.
