CSS3 transition events

Question

Are there any events fired by an element to check wether a css3 transition has started or end?

Answer 1

Webkit has this implemented only for transition end it would appear.

You can set a handler for a DOM event that is sent at the end of a transition. The event is an instance of WebKitTransitionEvent and its type is webKitTransitionEnd in JavaScript.

For example, the JavaScript code in Listing 6 displays an alert panel whenever a transition ends.

Listing 6 Handling transition end event

box.addEventListener( 'webkitTransitionEnd', 
    function( event ) { alert( "Finished transition!" ); }, false );

Opera

There is one type of transition event available. The oTransitionEnd event occurs at the completion of the transition.
