AnimationEffectTimingReadOnly

The AnimationEffectTimingReadOnly interface of the Web Animations API is comprised of timing properties.

This object is returned by the timing attribute of a KeyframeEffectReadOnly and AnimationEffectReadOnly interfaces.

Properties

AnimationEffectTimingReadOnly.delayRead only

The number of milliseconds to delay the start of the animation. Defaults to 0.

AnimationEffectTimingReadOnly.directionRead only

Whether the animation runs forwards (normal), backwards (reverse), switches direction after each iteration (alternate), or runs backwards and switches direction after each iteration (alternate-reverse). Defaults to normal.

AnimationEffectTimingReadOnly.durationRead only

The number of milliseconds each iteration of the animation takes to complete. Defaults to 0.

AnimationEffectTimingReadOnly.easingRead only

The rate of the animation's change over time. Accepts the pre-defined values linear, ease, ease-in, ease-out, and ease-in-out, or a custom cubic-bezier value like cubic-bezier(0.42, 0, 0.58, 1). Defaults to linear.

AnimationEffectTimingReadOnly.endDelayRead only

The number of milliseconds to delay after the end of an animation. This is primarily of use when sequencing animations based on the end time of another animation. Defaults to 0.

AnimationEffectTimingReadOnly.fillRead only

Dictates whether the animation's effects should be reflected by the element(s) state prior to playing (backwards), retained after the animation has completed playing (forwards), or both. Defaults to none.

AnimationEffectTimingReadOnly.iterationStartRead only

A number representing which repetition the animation begins at and its progress through it.

AnimationEffectTimingReadOnly.iterationsRead only

The number of times the animation should repeat. Defaults to 1, and can also take a value of infinity to make it repeat infinitely.
