Question

I\'d like to delete an object after it\'s done animating with a CSS transition, but I\'m not able to use a JavaScript library.

How do I detect when the animation is

Answer 1

element.addEventListener('transitionend', function(event) {
    alert("CSS Property completed: " + event.propertyName);

There is a single event that is fired when transitions complete.
In all standard-compliant browser, the event is transitionend,
in WebKit it is webkitTransitionEnd.

Here's the fiddle for Webkit: http://jsfiddle.net/bNgWY/
