## Overview

Build maintainable CSS systems using methodologies like BEM (Block Element Modifier), SMACSS, and CSS-in-JS patterns with proper organization and conventions.

## When to Use

- Large-scale stylesheets
- Component-based styling
- Design system development
- Multiple team collaboration
- CSS scalability and reusability

## Quick Start

Minimal working example:

```css
/* Block - standalone component */
.button {
  display: inline-block;
  padding: 10px 20px;
  border: none;
  border-radius: 4px;
  cursor: pointer;
  font-size: 16px;
  transition: all 0.3s ease;
}

/* Element - component part */
.button__icon {
  margin-right: 8px;
  vertical-align: middle;
}

/* Modifier - variant */
.button--primary {
  background-color: #007bff;
  color: white;
}

.button--primary:hover {
  background-color: #0056b3;
// ... (see reference guides for full implementation)
```
