The CSS includes a CSS feature query using the @supports
at-rule
, containing one style rule. This will be the first CSSRule returned by document.styleSheets[0].cssRules
.
myRules[0]
therefore returns a CSSSupportsRule
object.
@supports (display: grid) {
body {
color: blue;
}
}
let myRules = document.styleSheets[0].cssRules;
console.log(myRules[0]); // a CSSSupportsRule representing the feature query.
