CSS Transition Events

CSS

The CSS Transitions specification specifies that transition events are sent when a transition is enqueued, starts, ends, or is canceled as transitionrun, transitionstart, transitionend, and transitioncancel respectively. These events mirror the CSS animation events which allow developers to observe CSS animations.
