This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The selectorText property of the CSSStyleRule interface gets and sets the selectors associated with the CSSStyleRule.
A string.
The CSS includes one style rule. This will be the first CSSRule returned by document.styleSheets[0].cssRules. myRules[0].selectorText therefore returns a literal string of the selector, in this case "h1".
h1 {
color: pink;
}
let myRules = document.styleSheets[0].cssRules; console.log(myRules[0].selectorText); // a string containing "h1".
