Author components worthy of a library: each one is a self-contained HTML block that renders correctly inside any daisyUI theme and teaches the reader something.
Anatomy of a library component
- Name — concrete, not cute ("Editorial Hero", not "Hero Deluxe").
- Subtitle — what it is in one line.
- Code — complete HTML, no external dependencies beyond Tailwind/daisyUI.
- Preview — the same markup rendered live.
- Notes — usage, rules, variations.
Code rules
- Use daisyUI semantic classes (
btn,card,badge) + Tailwind utilities. Never raw hex colors when a semantic token exists —bg-primarysurvives re-theming,bg-[#e8704f]doesn't. - Opacity modifiers over semantic tokens (
text-base-content/60) give you the dim-scale for free. - One
<style>attribute allowed per component for font-family hooks; everything else stays class-based. - No JavaScript unless interaction demands it; prefer
<details>, popovers, and CSS-only patterns. - Placeholder images:
https://picsum.photos/seed/<seed>/<w>/<h>— seeded so previews stay stable. - Accessible by construction: real
<button>/<a>, visible labels, alt text that describes content.
Preview rules
The preview renders inside the live site's theme — which is exactly the point: if your component looks wrong in the preview frame, it will look wrong in users' themes. Keep previews compact (constrain widths, trim list lengths) but never alter the structure between code and preview_html.
Notes rules
- Usage: when to reach for this component.
- Rules: 4–6 hard rules, each one sentence, imperative voice.
- Variations: 2–3 named variants with the single change that creates them.
Anti-patterns
- Components tuned to one theme's colors ("looks broken in light mode").
- Fixed pixel widths instead of max-widths and grids.
- Icon fonts or CDN scripts — inline SVG or glyphs only.
- Dummy text like "Lorem ipsum" — write real microcopy; it doubles as usage documentation.
