Mastering Tailwind CSS: From Zero to Hero

# Mastering Tailwind CSS

Tailwind CSS has revolutionized how developers approach styling. Instead of writing custom CSS, you compose designs using utility classes directly in your HTML.

## Why Developers Love Tailwind

- **Rapid Development**: Build UIs faster without context-switching
- **Consistency**: Design tokens ensure visual consistency
- **Flexibility**: Customize everything without fighting the framework
- **Performance**: PurgeCSS removes unused styles automatically

## Getting Started

```bash
npm install -D tailwindcss postcss autoprefixer
npx tailwindcss init -p
```

Configure your `tailwind.config.js`:

```javascript
module.exports = {
content: [
'./templates/**/*.html',
'./static/**/*.js',
],
theme: {
extend: {
colors: {
primary: '#667eea',
secondary: '#764ba2',
},
},
},
plugins: [],
}
```

## Essential Utility Classes

### Layout

```html
<div class="container mx-auto px-4">
<div class="flex flex-wrap -mx-4">
<div class="w-full md:w-1/2 lg:w-1/3 px-4">
<!-- Content -->
</div>
</div>
</div>
```

### Typography

```html
<h1 class="text-4xl font-bold text-gray-900">Heading</h1>
<p class="text-lg text-gray-600 leading-relaxed">
Paragraph text with relaxed line height.
</p>
```

### Spacing

```html
<div class="p-6 m-4 space-y-4">
<div class="mb-4">Margin bottom</div>
<div class="mt-8">Margin top</div>
</div>
```

## Responsive Design

Tailwind uses mobile-first breakpoints:

- `sm`: 640px
- `md`: 768px
- `lg`: 1024px
- `xl`: 1280px
- `2xl`: 1536px

```html
<div class="w-full md:w-1/2 lg:w-1/3">
<!-- Full width on mobile, half on tablet, third on desktop -->
</div>
```

## Component Patterns

### Card Component

```html
<div class="bg-white rounded-lg shadow-lg overflow-hidden">
<img class="w-full h-48 object-cover" src="..." alt="...">
<div class="p-6">
<h3 class="text-xl font-bold mb-2">Card Title</h3>
<p class="text-gray-600">Card description goes here.</p>
<button class="mt-4 bg-primary text-white px-4 py-2 rounded-lg
hover:bg-opacity-90 transition-colors">
Learn More
</button>
</div>
</div>
```

### Button Variants

```html
<!-- Primary -->
<button class="bg-blue-600 text-white px-6 py-2 rounded-lg
hover:bg-blue-700 transition-colors">
Primary
</button>

<!-- Outline -->
<button class="border-2 border-blue-600 text-blue-600 px-6 py-2 rounded-lg
hover:bg-blue-600 hover:text-white transition-colors">
Outline
</button>
```

## Dark Mode

Enable dark mode in your config:

```javascript
module.exports = {
darkMode: 'class', // or 'media'
// ...
}
```

Use dark mode variants:

```html
<div class="bg-white dark:bg-gray-900 text-gray-900 dark:text-white">
<!-- Adapts to dark mode -->
</div>
```

## Optimization

Remove unused CSS in production:

```bash
NODE_ENV=production npx tailwindcss -o build.css --minify
```

## Pro Tips

1. **Use @apply sparingly**: Keep utilities in HTML when possible
2. **Create design tokens**: Define colors, spacing, etc. in config
3. **Use plugins**: Extend with forms, typography, and more
4. **Component extraction**: For repeated patterns, create components
