Summary
The animation-play-state CSS property determines whether an animation is running or paused. This can be queried to determine whether or not the animation is currently running. In addition, its value can be set to pause and resume playback of an animation.
Resuming a paused animation will start the animation from where it left off at the time it was paused, rather than starting over from the beginning of the animation sequence.

[1] In addition to the unprefixed support, Gecko 44.0 (Firefox 44.0 / Thunderbird 44.0 / SeaMonkey 2.41) added support for a -webkit prefixed version of the property for web compatibility reasons behind the preference layout.css.prefixes.webkit, defaulting to false. Since Gecko 49.0 (Firefox 49.0 / Thunderbird 49.0 / SeaMonkey 2.46) the preference defaults to true.
