CSSKeyframeRule: keyText property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2015.

The keyText property of the CSSKeyframeRule interface represents the keyframe selector as a comma-separated list of percentage values. The from and to keywords map to 0% and 100%, respectively.

Value

A string.

Exceptions

SyntaxError

Thrown if keyText is updated with an invalid keyframe selector, in which case keyText remains untouched.

Examples

The CSS includes a keyframes at-rule. This will be the first CSSRule returned by document.styleSheets[0].cssRules. myRules[0] returns a CSSKeyframesRule object, which will contain individual CSSKeyFrameRule objects for each keyframe.

css
@keyframes slide-in {
  from {
    transform: translateX(0%);
  }

  to {
    transform: translateX(100%);
  }
}
js
let myRules = document.styleSheets[0].cssRules;
let keyframes = myRules[0]; // a CSSKeyframesRule
console.log(keyframes[0].keyText); // a string containing 0%
