Tailwind CSS Component Patterns

Status: Production Ready ✅ Last Updated: 2026-01-14 Tailwind Compatibility: v3.x and v4.x Source: Production projects, shadcn/ui patterns

Quick Start

Essential Patterns

// Section Container
<section className="max-w-7xl mx-auto px-4 sm:px-6 lg:px-8 py-16 sm:py-24">
  {/* content */}
</section>

// Card Base
<div className="bg-card text-card-foreground rounded-lg border border-border p-6">
  {/* content */}
</div>

// Button Primary
<button className="bg-primary text-primary-foreground px-4 py-2 rounded-md hover:bg-primary/90 transition-colors">
  Click me
</button>

// Responsive Grid
<div className="grid grid-cols-1 md:grid-cols-2 lg:grid-cols-3 gap-6">
  {/* items */}
</div>

Spacing Scale

Consistent spacing prevents design drift:

Standard Pattern: Use increments of 4 (4, 6, 8, 12, 16, 24)

Responsive Breakpoints

Mobile-first approach (base styles = mobile, add larger breakpoints):

// Mobile: 1 column, Tablet: 2 columns, Desktop: 3 columns
<div className="grid grid-cols-1 md:grid-cols-2 lg:grid-cols-3 gap-6">

Container Patterns

Navigation Patterns

Header with Logo

<header className="sticky top-0 z-50 w-full border-b border-border bg-background/95 backdrop-blur">
  <div className="max-w-7xl mx-auto px-4 sm:px-6 lg:px-8">
    <div className="flex h-16 items-center justify-between">
      <div className="flex items-center gap-8">
        {/* Logo */}
        <a href="/" className="font-bold text-xl">Brand</a>

        {/* Desktop Nav */}
        <nav className="hidden md:flex gap-6">
          <a href="#" className="text-sm hover:text-primary transition-colors">Features</a>
          <a href="#" className="text-sm hover:text-primary transition-colors">Pricing</a>

</header>

Footer

<footer className="border-t border-border bg-muted/50">

      <div>
        <h4 className="font-semibold mb-4">Product</h4>
        <ul className="space-y-2 text-sm text-muted-foreground">
          <li><a href="#" className="hover:text-primary">Features</a></li>
          <li><a href="#" className="hover:text-primary">Pricing</a></li>
        </ul>
      </div>
      {/* More columns */}
    </div>
  </div>
</footer>

See references/navigation-patterns.md for mobile menus and dropdowns.

Dark Mode Support

All patterns use semantic color tokens that automatically adapt:

Never use raw colors like bg-blue-500 - always use semantic tokens.

See references/dark-mode-patterns.md for theme toggle implementation.

Common Class Combinations

Section with Heading

<section className="py-16 sm:py-24">
  <div className="max-w-7xl mx-auto px-4 sm:px-6 lg:px-8">
    <h2 className="text-3xl sm:text-4xl font-bold text-center mb-12">
      Section Title
    </h2>
    <div className="grid grid-cols-1 md:grid-cols-3 gap-6">
      {/* content */}
    </div>
  </div>
</section>

Centered Content

<div className="flex flex-col items-center justify-center text-center">
  <h1 className="text-4xl font-bold mb-4">Centered Title</h1>
  <p className="text-muted-foreground max-w-2xl">Centered description</p>
</div>

Hover Effects

// Lift on hover
<div className="transition-transform hover:scale-105">

// Shadow on hover
<div className="transition-shadow hover:shadow-lg">

// Color change on hover
<button className="transition-colors hover:bg-primary/90">

Critical Rules

✅ Always Do

1. Use semantic color tokens (bg-card, text-foreground)
2. Apply mobile-first responsive design (base → sm: → md:)
3. Use consistent spacing scale (4, 6, 8, 12, 16, 24)
4. Add transition-* classes for smooth interactions
5. Test in both light and dark modes

❌ Never Do

1. Use raw Tailwind colors (bg-blue-500 breaks themes)
2. Skip responsive prefixes (mobile users suffer)
3. Mix spacing scales randomly (creates visual chaos)
4. Forget hover states on interactive elements
5. Use fixed px values for text (text-base not text-[16px])

Template Components

Ready-to-use components in templates/components/:

• hero-section.tsx - Responsive hero with CTA
• feature-grid.tsx - 3-column feature grid with icons
• contact-form.tsx - Full form with validation styles
• footer.tsx - Multi-column footer with links

Copy and customize for your project.
