# CSS effects

One can get notifies when CSS transitions or animations finish.

Here CSS transitions or animations is triggered by adding a `className` to an element. Transitions or animations on the element and all its descendants will be listened and be waited for.

runCSSAnimation(element, className, function () {
    console.log('Animation finished');
});

// or alternatively use the promise returned
var promise = runCSSAnimation(element, className);
