📱 Responsive Design with CSS Media Queries

Responsive design ensures websites look great on all devices, from desktops to smartphones.

🧪 What Are Media Queries?

Media queries allow CSS to adapt styles based on:

  • 📏 Screen size
  • 🖼️ Resolution
  • 🔄 Orientation
@media (max-width: 768px) {
  body {
    font-size: 16px;
  }
}

✅ Applies styles only when the viewport is 768px wide or less.

🎯 Why It Matters
