Modern CSS3 - Grid + Flexbox layouts, custom properties (CSS variables), container queries, color-mix(), :has() selectors, logical properties, prefers-reduced-motion fallbacks. 8 style presets (Vanilla / Tailwind config / Sass / CSS Modules / BEM / Atomic utility / Print stylesheet / Animation). Mobile-first by default with container queries where they beat media queries.
Yes - a complete component stylesheet costs ~1,000 tokens on Qwen 3 Coder, inside the 2,500 anonymous / 10,000 signed-up daily pool. Premium Claude Sonnet / GPT-5 available per-call for complex multi-component design systems.
v0 by Vercel (free tier + $20/mo Pro) generates React + Tailwind components. Tailwind UI ($299 lifetime) is a paid component library. Cursor ($20/mo) and Copilot ($10-39/mo) help inside an IDE. Our tool is one-shot CSS - paste a description, get cross-browser-safe CSS. Pairs well with Tailwind: switch the preset to Tailwind config and we will write a tailwind.config.js + utility classes instead of raw CSS.
Yes - CSS custom properties for theming, @layer for cascade control, container queries (@container) where parent-relative sizing beats viewport, :has() for parent-based styling, color functions like color-mix() and OKLCH for accessible color manipulation. Falls back gracefully where needed.
Pick the Tailwind config preset. Output is Tailwind 3.x utility classes wired to your tailwind.config.js (which we generate alongside if you ask for theme customization). For the HTML markup that wraps the classes, switch to /code/html/ and pick the Tailwind preset.
Pick the Sass preset. Output uses .scss syntax with @use modules (not the deprecated @import), nesting where it aids clarity (not as decoration), @mixin for reusable patterns, @function for value computation. Compatible with Dart Sass 1.50+.
Pick the Animation preset. Output uses @keyframes with cubic-bezier timing, prefers-reduced-motion: reduce overrides for accessibility, will-change only on properties that animate. CSS-only where possible (transforms, opacity); JavaScript hooks suggested only for non-CSS-able effects.
Both - pick BEM for .block__element--modifier naming, or Atomic utility for single-purpose classes. For component-scoped CSS without naming collisions pick CSS Modules, which generates locally-scoped class names.
Yes - every preset uses CSS custom properties keyed off [data-theme=dark] plus a prefers-color-scheme: dark media query fallback. Toggling theme is a one-line attribute swap, no CSS recompile. Tailwind preset uses the built-in dark: variant.
Targets evergreen Chrome / Firefox / Safari (the last two stable releases). Uses @supports blocks for cutting-edge features (:has(), container queries) where Safari 16+ matters. Falls back to flexbox where older Safari fights you. For IE11 support - sorry, you should use /code/refactor/ to manually backport the output.
Pick the Print stylesheet preset. Output wraps everything in @media print, sets color-adjust: exact for backgrounds, hides nav and chrome, sizes images sensibly, breaks pages cleanly with break-inside: avoid on cards. Page-orientation hint via @page.
Yes - POST to /v1/chat/ with the same system prompt this page builds. Bearer auth, rate-limited. Good for design-token pipelines or component-library generators. Docs at /api/.
