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.currentTime property of the Web Animations API returns and sets the current time value of the animation in milliseconds, whether running or paused.

If the animation lacks a timeline, is inactive, or hasn't been played yet, currentTime's return value is null.


var currentTime = element.currentTime;
element.currentTime = someValue;


A number representing the current time in milliseconds, or null.


In the Drink Me/Eat Me game, Alice's height is animated so it can go from small to large or large to small. At the start of the game, her height is set between the two extremes by setting her animation's currentTime to half her keyframeEffect's duration:

aliceChange.currentTime = aliceChange.effect.timing.duration / 2;

A more generic means of seeking to the 50% mark of an animation would be:

animation.currentTime =
  animation.effect.getComputedTiming().delay +
  animation.effect.getComputedTiming().activeDuration / 2;
