You can try out the code from http://jsbin.com/husamupi/1/edit I had the same problem and could solve it

Do I use a callback or custom event somehow? element.addEventListener('transitionend', function(event) { alert("CSS Property completed: " + event.propertyName); }, false ); For now, the exact event name has not been standardized. Here's a quote from MDN : 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 .
