This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
var keyframes = new keyframeEffectReadOnly(element, keyframeSet, keyframeOptions);
- The DOM element to be animated, or
- A keyframe object or
- keyframeOptions Optional
- Either an integer representing the animation's duration (in milliseconds), or an
Objectcontaining one or more of the following:
- The number of milliseconds to delay the start of the animation. Defaults to
- 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
- The number of milliseconds each iteration of the animation takes to complete. Defaults to
- The rate of the animation's change over time. Accepts the pre-defined values
ease-in-out, or a custom cubic-bezier value like
cubic-bezier(0.42, 0, 0.58, 1). Defaults to
- 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
- Dictates whether the animation's effects should be reflected by the element(s) prior to playing (
backwards), retained after the animation has completed playing (
both. Defaults to
- Describes at what point in the iteration the animation should start.
0.5would indicate starting halfway through the first iteration for example, and with this value set, an animation with 2 iterations would end halfway through a third iteration. Defaults to
- The number of times the animation should repeat. Defaults to
1, and can also take a value of infinity to make it repeat infinitely.
The following options are currently not shipped anywhere, but will be added in the near future:
- Determines how values are combined between this animation and the element's underlying values.
- Determines how values build from iteration to iteration in the current animation.
- Determines how keyframes without temporal offsets should be distributed during the animation's duration.
