This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The 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.

Constructor

Animation()
Creates a new Animation object instance.

Properties

Animation.currentTime
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, its value is null.
Animation.effect
Gets and sets the AnimationEffectReadOnly associated with this animation. This will usually be a KeyframeEffect object.
Animation.finished Read only
Returns the current finished Promise for this animation.
Animation.id
Gets and sets the String used to identify the animation.
Animation.pending Read only
Indicates whether the animation is currently waiting for an asynchronous operation such as initiating playback or pausing a running animation.
Animation.playState Read only
Returns an enumerated value describing the playback state of an animation.
Animation.playbackRate
Gets or sets the playback rate of the animation.
Animation.ready Read only
Returns the current ready Promise for this animation.
Animation.startTime
Gets or sets the scheduled time when an animation's playback should begin.
Animation.timeline
Gets or sets the timeline associated with this animation.

Event handlers

Animation.oncancel
Gets and sets the event handler for the cancel event.
Animation.onfinish
Gets and sets the event handler for the finish event.

Methods

Animation.cancel()
Clears all keyframeEffects caused by this animation and aborts its playback.
Animation.finish()
Seeks either end of an animation, depending on whether the animation is playing or reversing.
Animation.pause()
Suspends playing of an animation.
Animation.play()
Starts or resumes playing of an animation, or begins the animation again if it previously finished.
Animation.reverse()
Reverses playback direction, stopping at the start of the animation. If the animation is finished or unplayed, it will play from end to beginning.
Animation.updatePlaybackRate()
Sets the speed of an animation after first synchronizing its playback position.

Accessibility concerns

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.
