A minimal CSS framework, built upon UnoCSS.
It extends the Tailwind CSS reset, adds sensible global defaults as well as some generic rules and shortcuts.
Sometimes, you may want to use all the power of an on-demand utility engine like UnoCSS or Tailwind, but write custom CSS as well, while accessing the color, spacing variables etc. you've defined in your configuration. That's where DueCSS bridges the gap.
- 🧶 Resilient set of base styles and utilities
- 🧩 Typography plugin
- 🌙 Dark mode based on CSS custom properties
- 🏵 Works well for traditional setups like Kirby CMS
Projects demonstrating the capabilities of DueCSS:

# pnpm
pnpm add -D duecss
# npm
npm i -D duecss
# yarn
yarn add -D duecss-
Create a
unocss.config.ts(orunocss.config.js) inside your UnoCSS project. To overwrite the default colors, create aprimaryandaccententry with some shades:Example:
import { defineConfig, presetUno } from 'unocss' import { presetDue } from 'duecss' export default defineConfig({ theme: { colors: { primary: { DEFAULT: '#943D40', 50: '#DDACAE', 100: '#D79D9F', 200: '#CB8183', 300: '#BF6467', 400: '#B1494C', 500: '#943D40', 600: '#6C2D2F', 700: '#451C1E', 800: '#1D0C0C', 900: '#000000' }, accent: { DEFAULT: '#C3A19D', 50: '#FFFFFF', 100: '#FFFFFF', 200: '#F1EAE9', 300: '#E2D2D0', 400: '#D2B9B6', 500: '#C3A19D', 600: '#AE807A', 700: '#95615B', 800: '#724A46', 900: '#4F3430' } } }, presets: [presetUno(), presetDue()] })
Now, you can use color utilities like
text-primary,bg-accent-300etc. -
Include the DueCSS base.
If you're using Sass, you can import DueCSS right into your main stylesheet (given a Vite context to resolve the import):
@use 'duecss/reset'; @use 'duecss/base';
You could also import DueCSS before your main CSS entrypoint in your main script:
import 'duecss/base.css' import './main.css' import 'uno.css'
-
For further customization like, overwrite the main global CSS custom properties:
:root { --du-font-family-normal: 'HK Grotesk', system-ui; --du-font-family-heading: 'Petunia Sans', sans-serif; --du-text-scale-ratio: 1.333; }
With these applied, you can use utilities like
font-normalorfont-headingin your components.
For a full list of global custom properties, take a look inside base.css.
To enable the dark mode on the whole document or apply it to a container only, use the data-theme attribute:
<html data-theme="dark"></html>With the dark mode applied, all contrast colors will be inverted. Background and foreground color will be managed by the attribute as well.
To access and reuse primary and accent colors in your CSS, you can add the primary and accent colors to your :root element:
<html
class="due-var-color-primary due-var-color-accent due-var-color-accent-700"
lang="en"
/>DueCSS will then generate and include the following global CSS custom properties:
.due-var-color-accent {
--du-color-accent: #c3a19d;
}
.due-var-color-accent-700 {
--du-color-accent-700: #95615b;
}
.due-var-color-primary {
--du-color-primary: #943d40;
}Now you can reference to these color variables everywhere in your CSS code.
DueCSS lets you use Animate.css by providing UnoCSS rules that provide utility-first access to the animations.
<h1 class="animated animated-bounce animated-infinite">

| Class | Properties |
