CSSCounterStyleRule: system property
Baseline
2023
Newly available
Since September 2023, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.
The system property of the CSSCounterStyleRule interface gets and sets the value of the system descriptor. If the descriptor does not have a value set, this attribute returns an empty string.
Value
A string.
Examples
The following example shows a @counter-style rule. In JavaScript, myRules[0] is this @counter-style rule, returning system gives us the value "fixed".
css
@counter-style box-corner {
system: fixed;
symbols: ◰ ◳ ◲ ◱;
suffix: ": ";
}
js
let myRules = document.styleSheets[0].cssRules;
console.log(myRules[0].system); // "fixed"
