Production-ready CSS,
copy-paste honest.

What makes it different

• →
  Code that actually ships.Every demo is responsive at any viewport, keyboard-accessible, and respects prefers-reduced-motion. The gallery preview and your paste produce the same result — no "looks good in the screenshot" trap.
• →
  Vanilla CSS first.Modern selectors (:has(), :focus-visible, @property, container queries) where they pull weight. JS only when interaction genuinely needs it. Works in any stack — React, Vue, Svelte, Astro, plain HTML.
• →
  Built for AI-assistant workflows.The site publishes llms.txt and llms-full.txt manifests so AI assistants can extract working code instead of guessing from rendered HTML. Few sites do this; the ones that do get cited disproportionately.
• →
  Open source companion.The most-used CSS tools also ship as framework-free single-HTML files at github.com/codefronts/toolkit — fork, self-host, or drop into any project.
• →
  100% client-side.Tools and generators run in your browser. Analytics is limited to anonymised page-view counting (Google Analytics 4 + Fullres, a cookieless GDPR-friendly tracker) — no telemetry, no cross-site tracking, no signup.

What's shipped

Real numbers, not "100+ components" claims. Updated when content ships.

Plus 18 navigation collections, 22 UI snippet collections, and 13 design-style collections — 150 total content collections. Recent additions worth a look: 24 CSS timelines, 30 CSS badges, and CSS accordions.

Standards we keep

Every demo on the site is held to these:

• ✓
  Semantic HTML. Real <button>, <form>, <details>, <dialog> — not <div> + ARIA when the platform has a built-in element.
• ✓
  Keyboard navigable. Every interactive demo works with Tab + Enter / Space, shows a visible focus ring, and doesn't depend on hover.
• ✓
  Responsive by default. Demos render correctly at 320 px, 600 px, and 1200 px. Defensive CSS on every demo root.
• ✓
  Honest counts and labels. Hero meta pills, intro paragraphs, and thumbnail headlines are computed from the data — never hardcoded. If we say "39 components," there are 39 components.
• ✓
  Reduced motion respected. Every demo with continuous motion honors prefers-reduced-motion: reduce.
• ✓
  No two-copy traps. What you see in the gallery preview is what you get when you paste — same exact code. Audited.

Why it exists

CodeFronts started because too many "free CSS component" sites publish code that breaks the moment you paste it into a real project — broken at 320 px, broken when the container is 280 px, broken with keyboard, broken without hover. We built one where every demo is held to a real production standard — what you copy is what works.
