Animation

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.

The Animation.effect property of the Web Animations API gets and sets the target effect of an animation. The target effect may be either an effect object of a type based on AnimationEffect, such as KeyframeEffect, or null.

The Animation.finished read-only property of the Web Animations API returns a Promise which resolves once the animation has finished playing.

The Animation.id property of the Web Animations API returns or sets a string used to identify the animation.

The overallProgress read-only property of the Animation interface returns a number between 0 and 1 indicating the animation's overall progress towards its finished state. This is the overall progress across all of the animation's iterations, not each individual iteration.

The read-only Animation.pending property of the Web Animations API indicates whether the animation is currently waiting for an asynchronous operation such as initiating playback or pausing a running animation.

The Animation.playbackRate property of the Web Animations API returns or sets the playback rate of the animation.

The read-only Animation.playState property of the Web Animations API returns an enumerated value describing the playback state of an animation.

The read-only Animation.ready property of the Web Animations API returns a Promise which resolves when the animation is ready to play. A new promise is created every time the animation enters the "pending" play state as well as when the animation is canceled, since in both of those scenarios, the animation is ready to be started again.

The read-only Animation.replaceState property of the Web Animations API indicates whether the animation has been removed by the browser automatically after being replaced by another animation.

The Animation.startTime property of the Animation interface is a double-precision floating-point value which indicates the scheduled time when an animation's playback should begin.

The Animation.timeline property of the Animation interface returns or sets the timeline associated with this animation. A timeline is a source of time values for synchronization purposes, and is an AnimationTimeline-based object. By default, the animation's timeline and the Document's timeline are the same.

The Web Animations API's cancel() method of the Animation interface clears all KeyframeEffects caused by this animation and aborts its playback.

The commitStyles() method of the Web Animations API's Animation interface writes the computed values of the animation's current styles into its target element's style attribute.

The finish() method of the Web Animations API's Animation Interface sets the current playback time to the end of the animation corresponding to the current playback direction.

The pause() method of the Web Animations API's Animation interface suspends playback of the animation.

The persist() method of the Web Animations API's Animation interface explicitly persists an animation, preventing it from being automatically removed when it is replaced by another animation.

The play() method of the Web Animations API's Animation Interface starts or resumes playing of an animation. If the animation is finished, calling play() restarts the animation, playing it from the beginning.

The Animation.reverse() method of the Animation Interface reverses the playback direction, meaning the animation ends at its beginning. If called on an unplayed animation, the whole animation is played backwards. If called on a paused animation, the animation will continue in reverse.

The updatePlaybackRate() method of the Web Animations API's Animation Interface sets the speed of an animation after first synchronizing its playback position.
