Service components in ngAnimate

The $animateCss service is a useful utility to trigger customized CSS-based transitions/keyframes from a JavaScript-based animation or directly from a directive. The purpose of $animateCss is NOT to side-step how $animate and ngAnimate work, but the goal is to allow pre-existing animations or directives to create more complex animations that can be purely driven using CSS code.

The ngAnimate $animate service documentation is the same for the core $animate service.
