Window: animationstart event
The animationstart
event is fired when a CSS Animation has started. If there is an animation-delay
, this event will fire once the delay period has expired. A negative delay will cause the event to fire with an elapsedTime
equal to the absolute value of the delay (and, correspondingly, the animation will begin playing at that time index into the sequence).

Interface | AnimationEvent |
Event handler property | onanimationstart |
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: animationstart.
Examples
This listens for the animationstart
event and logs a message when it is fired:
window.addEventListener('animationstart', () => {
console.log('Animation started');
});
The same, but using onanimationstart
:
window.onanimationstart = () => {
console.log('Animation started');
};
