Examples

The CSS includes one style rule. This will be the first CSSRule returned by document.styleSheets[0].cssRules. myRules[0] therefore returns a CSSStyleRule object representing the rule defined for h1. 

h1 {
  color: pink;
}

let myRules = document.styleSheets[0].cssRules;
console.log(myRules[0]); // a CSSStyleRule representing the h1.
