CSSKeyframesRule: cssRules property
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since August 2016.
The read-only cssRules property of the CSSKeyframeRule interface returns a CSSRuleList containing the rules in the keyframes at-rule.
Note:
The CSSKeyframeRule itself is indexable like an array, and functions similarly to its cssRules property.
Value
A CSSRuleList.
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. The cssRules property returns a CSSRuleList containing two rules.
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.cssRules); // a CSSRuleList object with two rules
