This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The target property of a KeyframeEffectReadOnly or a KeyframeEffect interface represents the element or pseudo-element being animated. It may be null for animations that do not target a specific element. It performs as both a getter and a setter, except with animations and transitions generated by CSS.
Note: For KeyframeEffect, this property is both a getter and a setter. For KeyframeEffectReadOnly, it is read-only.
var targetElement = document.getElementById("elementToAnimate");
var keyframes = new KeyframeEffect( targetElement, keyframeBlock, timingOptions );
// returns #elementToAnimate
keyframes.target;
// assigns keyframes a new target
keyframes.target = newTargetElement; An Element or null.
In the Follow the White Rabbit example, whiteRabbit sets the target element to be animated:
var whiteRabbit = document.getElementById("rabbit");
var rabbitDownKeyframes = new KeyframeEffect(
whiteRabbit,
[
{ transform: 'translateY(0%)' },
{ transform: 'translateY(100%)' }
],
{ duration: 3000, fill: 'forwards' }
);
// returns <div id="rabbit">Click the rabbit's ears!</div>
rabbitDownKeyframes.target;
