`css/require-font-display`

Require font-display in @font-face rules

Default severity: warning
Presets: opinionated, nuxt
Automatic fix: None; review the suggested change
Applies to: CSS inside SFC style blocks
Options: No rule-specific options. Severity and preset selection are configurable.

Configuration (Vite+)

import { defineConfig } from "@vizejs/vite-plugin/vite-plus";

export default defineConfig({
  lint: {
    vize: {
      "preset": "incremental",
      "rules": {
        "css/require-font-display": "warn"
      }
    },
  },
});

vp run lint

Bad

The font-face declaration defines the font source but omits its font-display policy.

<style>
@font-face {
  font-family: "Inter";
  src: url("/inter.woff2") format("woff2");
}
</style>

Good

font-display: swap explicitly selects the fallback-to-font display policy.

<style>
@font-face {
  font-family: "Inter";
  src: url("/inter.woff2") format("woff2");
  font-display: swap;
}
</style>

Good avoids this rule's finding under the configuration above; other rules may still report diagnostics.
