The basic preset for UnoCSS, with only the most essential utilities.

Source Code

Installation

pnpm

pnpm add -D @unocss/preset-mini

yarn

yarn add -D @unocss/preset-mini

npm

npm install -D @unocss/preset-mini

uno.config.ts

import presetMini from '@unocss/preset-mini'
import { defineConfig } from 'unocss'

export default defineConfig({
  presets: [
    presetMini(),
    // ...other presets
  ],
})

TIP

This preset is included in the unocss package, you can also import it from there:

import { presetMini } from 'unocss'

Rules

This preset is a subset of @unocss/preset-wind, containing only the most essential utilities aligned with CSS's properties, but excludes opinioned or complicated utilities introduced in Tailwind CSS (container, animation, gradient etc.). This can be a good starting point for your own custom preset on top of familiar utilities from Tailwind CSS or Windi CSS.

Features

Dark mode

By default, this preset generates class-based dark mode with dark: variant.

<div class="dark:bg-red:10" />

will generate:

.dark .dark\:bg-red\:10 {
  background-color: rgb(248 113 113 / 0.1);
}

To opt-in media query based dark mode, you can use @dark: variant:

<div class="@dark:bg-red:10" />

@media (prefers-color-scheme: dark) {
  .\@dark\:bg-red\:10 {
    background-color: rgb(248 113 113 / 0.1);
  }
}

Or set globally with the config for dark: variant

presetMini({
  dark: 'media'
})

CSS @layer

CSS's native @layer is supported with variant layer-xx:

<div class="layer-foo:p4" />
<div class="layer-bar:m4" />

will generate:

@layer foo {
  .layer-foo\:p4 {
    padding: 1rem;
  }
}
@layer bar {
  .layer-bar\:m4 {
    margin: 1rem;
  }
}

Theme

You can fully customize your theme property in your config, and UnoCSS will eventually deeply merge it to the default theme.

WARNING

breakpoints property isn't deeply merged, but overridden, see Breakpoints.

presetMini({
  theme: {
    // ...
    colors: {
      veryCool: '#0000ff', // class="text-very-cool"
      brand: {
        primary: 'hsl(var(--hue, 217) 78% 51%)', // class="bg-brand-primary"
      }
    },
  }
})
