Google Font Display

Enforce font-display behavior with Google Fonts.

Why This Error Occurred

For a Google Font, the font-display descriptor was either missing or set to auto, block, or fallback, which are not recommended.

Possible Ways to Fix It

For most cases, the best font display strategy for custom fonts is optional.

pages/index.js
import Head from 'next/head'
 
export default function IndexPage() {
  return (
    <div>
      <Head>
        <link
          href="https://fonts.googleapis.com/css2?family=Krona+One&display=optional"
          rel="stylesheet"
        />
      </Head>
    </div>
  )
}

Specifying display=optional minimizes the risk of invisible text or layout shift. If swapping to the custom font after it has loaded is important to you, then use display=swap instead.

When Not To Use It

If you want to specifically display a font using an auto, block, or fallback strategy, then you can disable this rule.
