📱 Module 11: Responsive Web Design

Responsive Web Design ensures your website looks and works great on all devices — desktops, tablets, and smartphones. 📲 CSS offers powerful tools like media queries, flexible layouts, and relative units to create responsive designs.

📐 Fluid Layouts

Use percentages instead of fixed widths:

.container {
  width: 100%;
  max-width: 1200px;
  margin: auto;
}
  

🔀 Media Queries

@media (max-width: 768px) {
  .sidebar {
    display: none;
  }
}
  

Media queries apply styles based on screen width, resolution, orientation, and more.

📏 Viewport Meta Tag

<meta name=\"viewport\" content=\"width=device-width, initial-scale=1.0\">
  

This tag ensures your layout scales correctly on mobile devices.

🔧 Flexible Units

• em, rem: Scalable text
• %: Responsive sizing
• vh, vw: Viewport-based units

✅ Summary

• Use fluid layouts, relative units, and media queries to adapt your site. 🧩
• Test across multiple devices and screen sizes.
• Responsive design improves user experience and SEO. 💡
