# Tailwind CSS - Responsive Design

Tailwind CSS provides a mobile-first responsive design system using breakpoint prefixes that make it easy to build adaptive layouts.

## Key Concepts

### Mobile-First Approach

Tailwind uses a mobile-first breakpoint system. Unprefixed utilities apply to all screen sizes, and breakpoint prefixes apply from that breakpoint and up:

```html
<!-- Mobile: full width, Tablet+: half width, Desktop+: third width -->
<div class="w-full md:w-1/2 lg:w-1/3">
  Responsive width
</div>
```

### Default Breakpoints

```javascript
// tailwind.config.js default breakpoints
{
  sm: '640px',   // Small devices (landscape phones)
  md: '768px',   // Medium devices (tablets)
  lg: '1024px',  // Large devices (desktops)
  xl: '1280px',  // Extra large devices (large desktops)
  '2xl': '1536px' // 2X large devices (larger desktops)
}
```

## Best Practices

### 1. Start Mobile, Scale Up

Design for mobile first, then add complexity for larger screens:

```html
<!-- Good: Mobile-first approach -->
<div class="
  flex flex-col
  md:flex-row
  gap-4
">
  <div class="w-full md:w-1/2">Column 1</div>
  <div class="w-full md:w-1/2">Column 2</div>
</div>

<!-- Bad: Desktop-first (requires more overrides) -->
<div class="
  flex flex-row
  sm:flex-col
">
```

### 2. Use Responsive Typography

Scale text appropriately across devices:

```html
<h1 class="
  text-2xl sm:text-3xl md:text-4xl lg:text-5xl xl:text-6xl
  font-bold
  leading-tight
">
  Responsive Heading
</h1>

<p class="
  text-sm sm:text-base md:text-lg
  leading-relaxed
">
  Body text that scales
</p>
```

### 3. Responsive Spacing

Adjust padding and margins for different screens:

```html
<div class="
  px-4 sm:px-6 md:px-8 lg:px-12
  py-8 md:py-12 lg:py-16
">
  <!-- Content with responsive padding -->
</div>

<section class="
  space-y-4 md:space-y-6 lg:space-y-8
">
  <!-- Responsive spacing between children -->
</section>
```

### 4. Grid Layouts

Create responsive grids that adapt to screen size:

```html
<!-- 1 column mobile, 2 tablet, 3 desktop, 4 large desktop -->
<div class="
  grid
  grid-cols-1
  sm:grid-cols-2
  lg:grid-cols-3
  xl:grid-cols-4
  gap-4 md:gap-6
">
  <div>Item 1</div>
  <div>Item 2</div>
  <div>Item 3</div>
  <div>Item 4</div>
</div>
```

### 5. Show/Hide Elements

Control visibility across breakpoints:

```html
<!-- Mobile menu button: visible on mobile, hidden on desktop -->
<button class="md:hidden">
  <svg><!-- Menu icon --></svg>
</button>

<!-- Desktop navigation: hidden on mobile, visible on desktop -->
<nav class="hidden md:flex space-x-6">
  <a href="#">Home</a>
  <a href="#">About</a>
  <a href="#">Contact</a>
</nav>

<!-- Show only on mobile -->
<div class="block md:hidden">Mobile only</div>

<!-- Show only on desktop -->
<div class="hidden lg:block">Desktop only</div>
```

## Examples

### Responsive Hero Section

<section class="
  relative
  min-h-screen md:min-h-[600px] lg:min-h-[800px]
  px-4 sm:px-6 lg:px-8
  py-12 md:py-16 lg:py-20
">
  <div class="
    max-w-7xl mx-auto
    flex flex-col md:flex-row
    items-center
    gap-8 md:gap-12
  ">
    <!-- Text Content -->
    <div class="
      w-full md:w-1/2
      text-center md:text-left
    ">
      <h1 class="
        text-3xl sm:text-4xl md:text-5xl lg:text-6xl
        font-bold
        mb-4 md:mb-6
      ">
        Welcome to Our Site
      </h1>
      <p class="
        text-base sm:text-lg md:text-xl
        text-gray-600
        mb-6 md:mb-8
      ">
        This is a responsive hero section that adapts to all screen sizes.
      </p>
      <button class="
        w-full sm:w-auto
        px-6 md:px-8
        py-3 md:py-4
        bg-blue-500 hover:bg-blue-600
        text-white
        text-base md:text-lg
        rounded-lg
      ">
        Get Started
      </button>
    </div>

    <!-- Image -->
    <div class="
      w-full md:w-1/2
      order-first md:order-last
    ">
      <img
        src="/hero.jpg"
        alt="Hero"
        class="

## Advanced Patterns

### Container Queries (Modern)

Use container queries for component-level responsiveness:

```javascript
// tailwind.config.js
module.exports = {
  plugins: [
    require('@tailwindcss/container-queries'),
  ],
}
```

```html
<div class="@container">
  <div class="
    @sm:grid @sm:grid-cols-2
    @lg:grid-cols-3
    gap-4
  ">
    <!-- Responsive to container, not viewport -->
  </div>
</div>
```
