CSSFontPaletteValuesRule: name property

Baseline 2022

Newly available

Since November 2022, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.

The read-only name property of the CSSFontPaletteValuesRule interface represents the name identifying the associated @font-palette-values at-rule. A valid name always starts with two dashes, such as --Alternate.

Value

A string beginning with two dashes.

Examples

Read the at-rule's name

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 name.

HTML

html
<pre id="log">The @font-palette-values at-rule's name:</pre>

CSS

css
@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;
}

JavaScript

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

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