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

read onlydelay:Float

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

read onlydirection:PlaybackDirection

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.

read onlyduration:EitherType<Float, String>

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

read onlyeasing:String

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.

read onlyendDelay:Float

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.

read onlyfill:FillMode

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.

read onlyiterationStart:Float

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

read onlyiterations:Float

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