Animation interface of the Web Animations API represents a single animation player and provides playback controls and a timeline for an animation node or source.

Stringused to identify the animation.
- Indicates whether the animation is currently waiting for an asynchronous operation such as initiating playback or pausing a running animation.
- Returns an enumerated value describing the playback state of an animation.
- Gets or sets the playback rate of the animation.
- Returns the current ready Promise for this animation.
- Returns the replace state of the animation. This will be
activeif the animation has been replaced, or
Animation.persist()has been invoked on it.
- Gets or sets the scheduled time when an animation's playback should begin.
- Gets or sets the
timelineassociated with this animation.
- Clears all
keyframeEffectscaused by this animation and aborts its playback.
- Commits the end styling state of an animation to the element being animated, even after that animation has been removed. It will cause the end styling state to be written to the element being animated, in the form of properties inside a
- Seeks either end of an animation, depending on whether the animation is playing or reversing.
- Suspends playing of an animation.
- Explicitly persists an animation, when it would otherwise be removed due to the browser's Automatically removing filling animations behavior.
- Starts or resumes playing of an animation, or begins the animation again if it previously finished.
- Reverses playback direction, stopping at the start of the animation. If the animation is finished or unplayed, it will play from end to beginning.
- Sets the speed of an animation after first synchronizing its playback position.
It is possible to trigger a large number of animations on the same element. If they are indefinite (i.e., forwards-filling), this can result in a huge animations list, which could create a memory leak. For this reason, modern browsers have implemented the part of the Web Animations spec that automatically removes overriding forward filling animations, unless the developer explicitly specifies to keep them.
animation.commitStyles()for commiting the end styling state of an animation to the element being animated, even after that animation has been removed.
animation.onremovefor setting and running an event handler that fires when the animation is removed (i.e., put into an

animation.replaceStateto return the replace state of the animation. This will be

Blinking and flashing animation can be problematic for people with cognitive concerns such as Attention Deficit Hyperactivity Disorder (ADHD). Additionally, certain kinds of motion can be a trigger for Vestibular disorders, epilepsy, and migraine, and Scotopic sensitivity.
Consider providing a mechanism for pausing or disabling animation, as well as using the Reduced Motion Media Query to create a complimentary experience for users who have expressed a preference for no animated experiences.
