CSSFontFeatureValuesRule: fontFamily property

Baseline 2023
Newly available

Since March 2023, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.

The fontFamily property of the CSSConditionRule interface represents the name of the font family it applies to.

Value

A string.

Examples

Read font family

In this example, we declare two @font-feature-values one for the Font One font family, and the other for Font Two. We then use the CSSOM to read these font families, displaying them into the log.

html
<pre id="log"></pre>

CSS

css
/* At-rule for "nice-style" in Font One */
@font-feature-values Font One {
  @styleset {
    nice-style: 12;
  }
}

/* At-rule for "nice-style" in Font Two */
@font-feature-values Font Two {
  @styleset {
    nice-style: 4;
  }
}

/* Apply the at-rules with a single declaration */
.nice-look {
  font-variant-alternates: styleset(nice-style);
}

JavaScript

js
const log = document.getElementById("log");
const rules = document.styleSheets[document.styleSheets.length - 1].cssRules;

const fontOne = rules[0]; // A CSSFontFeatureValuesRule
log.textContent = `The 1st '@font-feature-values' family: "${fontOne.fontFamily}".\n`;

const fontTwo = rules[1]; // Another CSSFontFeatureValuesRule
log.textContent += `The 2nd '@font-feature-values' family: "${fontTwo.fontFamily}".`;
