/* layer: default */
.font-lato {
  font-family: "Lato", sans-serif;
}
.font-lobster {
  font-family: "Lobster";
}
.font-mono {
  font-family: "Fira Code", "Fira Mono", ui-monospace, SFMono-Regular, Menlo,
    Monaco, Consolas, "Liberation Mono", "Courier New", monospace;
}
.font-sans {
  font-family: "Roboto", ui-sans-serif, system-ui, -apple-system,
    BlinkMacSystemFont, "Segoe UI", Roboto, "Helvetica Neue", Arial, "Noto Sans",
    sans-serif, "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol",
    "Noto Color Emoji";
}

Serve Fonts Locally

By default the preset will fetch the fonts from the provider's CDN. If you want to serve the fonts locally, you can download the fonts and serve them from your own server using the processor from @unocss/preset-web-fonts/local.

import presetWebFonts from '@unocss/preset-web-fonts'
import { createLocalFontProcessor } from '@unocss/preset-web-fonts/local'
import { defineConfig } from 'unocss'

export default defineConfig({
  presets: [
    presetWebFonts({
      provider: 'none',
      fonts: {
        sans: 'Roboto',
        mono: 'Fira Code',
      },
      // This will download the fonts and serve them locally
      processors: createLocalFontProcessor({
        // Directory to cache the fonts
        cacheDir: 'node_modules/.cache/unocss/fonts',

        // Directory to save the fonts assets
        fontAssetsDir: 'public/assets/fonts',

        // Base URL to serve the fonts from the client
        fontServeBaseUrl: '/assets/fonts'
      })
    }),
  ],
})

This will download the fonts assets to public/assets/fonts and serve them from /assets/fonts on the client. When doing this, please make sure the license of the fonts allows you to redistribute so, the tool is not responsible for any legal issues.
