fertig

A classless CSS framework for finished interfaces. Link one file and write semantic HTML; fertig styles the page, forms, tables, dialogs, popovers, navigation, feedback, and common layout patterns.

42.2 KB raw · 9.5 KB gzipped · no build step · no dependencies · no JavaScript.

Use

npm install fertig

@import "fertig";

Or use the CDN:

<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/fertig@5/fertig.min.css">

That is the complete setup. See the documentation, component catalogue, and copy-paste blocks.

What it includes

• Light and dark themes through light-dark()
• Accessible forms, input groups, one-time codes, listboxes, surfaces, cards, items, empty states, tabs, menus, dialogs, tooltips, and more
• Native no-JavaScript behavior for popovers, dialogs, drawers, disclosures, toasts, and tooltips
• Logical properties for RTL layouts
• OKLCH color ramps and WCAG AA semantic pairs
• A cascade layer, so unlayered project CSS overrides fertig cleanly

Seven component classes are optional: .row, .grid, .card, .badge, .muted, .center, and .wide. Layout utilities are available when semantic HTML alone cannot express the layout.

Customize

Override tokens in your own CSS:

:root {
  --fertig-ac: oklch(52% 0.18 270);
  --fertig-r: 10px;
  --fertig-w: 72rem;
}

Development

npm install
npm run hooks:install # enable automatic patch versioning for commits
npm run build       # regenerate fertig.min.css
npm test            # library and site tests
npm run site        # Astro production build
npm run site:serve  # Astro development server
npm run check       # complete release check

The package publishes only fertig.css, fertig.min.css, this README, and the MIT license. The Astro site lives in src/pages, with its shared shell in src/layouts and src/components.
