MDN’s new design is in Beta! A sneak peek: https://blog.mozilla.org/opendesign/mdns-new-design-beta/

This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

The animation-play-state CSS property specifies whether an animation is running or paused. In JavaScript, this can be queried to determine whether or not the animation is currently running. In addition, you can use JavaScript to set its value to pause or resume playback of an animation.

/* Single animation */
animation-play-state: running;
animation-play-state: paused;

/* Multiple animations */
animation-play-state: paused, running, running;

/* Global values */
animation-play-state: inherit;
animation-play-state: initial;
animation-play-state: unset;

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.

Note: When you specify multiple comma-separated values on an animation-* property, they will be assigned to the animations specified in the animation-name property in different ways depending on how many there are. For more information, see Setting multiple animation property values.

Formal syntax

<single-animation-play-state>#

where
<single-animation-play-state> = running | paused

[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.
