Tailwind CSS — Utility-first Styling Skill

When to use

• Rapid UI building with consistent spacing/typography scales
• Design systems where composition beats bespoke CSS
• Component-driven apps (React/Vue/Svelte), marketing pages, prototypes → production

Key concepts & patterns

• Utilities compose in HTML/JSX: class="flex gap-4 p-6 bg-zinc-950 text-white"
• Responsive variants: sm: md: lg: xl: etc.
• State variants: hover:, focus:, active:, disabled:, group-hover:, peer-checked:
• Arbitrary values (use sparingly): w-[42rem], bg-[#0b1220], translate-y-[3px]
• Dark mode patterns: dark: with class-based strategy
• Extracting repeated patterns:
  • Prefer components (JSX/Vue components) first
  • Then @apply for small reusable patterns (avoid overuse)
• Build pipeline:
  • Tailwind scans “content” files for class names and generates CSS (zero-runtime)
