Read associated font family using CSSOM

This example first defines an @import and an @font-palette-values at-rule. Then it reads the @font-palette-values rule and displays its name. As these rules live in the last stylesheet added to the document, the palette will be the second CSSRule returned by the last stylesheet in the document (document.styleSheets[document.styleSheets.length-1].cssRules). So, rules[1] returns a CSSFontPaletteValuesRule object, from which we can access fontFamily.


<pre id="log">The @font-palette-values at-rule font families:</pre>


@import url(https://fonts.googleapis.com/css2?family=Bungee+Spice);

@font-palette-values --Alternate {
  font-family: "Bungee Spice";
  override-colors: 0 #00ffbb, 1 #007744;

.alternate {
  font-palette: --Alternate;


const log = document.getElementById("log");

const rules = document.styleSheets[document.styleSheets.length - 1].cssRules;
const fontPaletteValuesRule = rules[1]; // aA CSSFontPaletteValuesRule interface
log.textContent += ` ${fontPaletteValuesRule.fontFamily}`;
