How Can I Reliably Detect the Completion of CSS3 Transitions Across Different Browsers?

Understanding CSS3 Transition Events: A Comprehensive Guide

CSS3 transitions provide a powerful way to animate element changes smoothly. While using transitions, developers may need to listen for events when a transition starts or ends to perform synchronization or conditional tasks.

W3C CSS Transitions Draft

According to the W3C CSS Transitions Draft, when a CSS transition completes, a corresponding DOM event is generated. This event is triggered specifically for each property undergoing a transition. This mechanism enables developers to link actions with the completion of a transition.

WebKit

In WebKit, the 'webkitTransitionEnd' event type is used to trap the completion of a transition. This event is an instance of WebKitTransitionEvent.

Mozilla

Mozilla implements a unified event called 'transitionend' that triggers when transitions complete. Similarly, in Opera, 'oTransitionEnd' serves the same purpose.

Opera

Opera supports a single transition event 'oTransitionEnd', which occurs at the transition's end.

Internet Explorer

For Internet Explorer, the 'transitionend' event signifies the completion of a transition. However, if the transition is removed before its completion, the event will not fire.

Cross-Browser Normalization

As different browsers have varying event names and implementations for transition events, it's helpful to use a cross-browser normalization strategy. One approach is to use the jQuery JavaScript library, which abstracts event handling across various browsers.
