A small, opinionated CSS framework to make sites look alright with minimal effort

⚠️ Work in progress. Things are most certainly incomplete and/or broken, and will definitely change.

• 🔥 Embraces semantic HTML to make native elements look great out of the box, without classes
• 😎 Small set of utilities for additional states and convenience
• 🐛 Tiny footprint with no runtime dependencies or build step required
• 🌈 Automatic color system that reduces time spent fiddling with color palettes
• 🪗 Fully responsive

From a CDN:

@import url("https://esm.sh/gh/andreasphil/[email protected]/dist/index.min.css")
layer(theme);

import { useThemeColor } from "https://esm.sh/gh/andreasphil/[email protected]";

With a package manager:

npm install github:andreasphil/design-system#<tag>

Find the demo at https://design-system.a13i.dev.

First, import the CSS. I recommend using layers to avoid conflicts and to avoid specificity chaos when customizing.

@import "@andreasphil/design-system/style.css" layer(theme);

@layer theme {
  /* You can add customizations and override variables here. */
}

There is a helper that will manage the theme color for light and dark mode automatically:

import { useThemeColor } from "@andreasphil/design-system";

const { unsubscribe } = useThemeColor();

// Call when you want to stop automatic theme color management
unsubscribe();

Design System is built with Lightning CSS. Packages are managed by pnpm. The following commands are available:

pnpm dev          # Compile stylesheets in watch mode
pnpm build        # Bundle for production

For a demo, open index.html in a browser.

Deployment should work out of the box when linking the repository to a project on Netlify.

This library uses a number of open source packages listed in package.json. Icons are from Lucide. It was inspired by Pico.css.

Thanks 🙏
