Introduction

Responsive design ensures your website looks great on any device, from desktop computers to mobile phones. With the right tools and techniques, you can create flexible layouts that adapt seamlessly to various screen sizes.

What is Responsive Design?

Core Principles of Responsive Design:

- **Fluid Grid Layouts**: Use percentage-based dimensions instead of fixed units.
- **Flexible Images**: Ensure images scale properly within their containers.
- **Media Queries**: Adjust styles based on the device's screen size.

Using CSS Media Queries:

Example: Applying Media Queries for Different Screen Sizes

/* Default styles */
body {
  font-family: Arial, sans-serif;
  font-size: 16px;
}

/* Tablet devices */
@media (max-width: 768px) {
  body {
    font-size: 14px;
  }
}

/* Mobile devices */
@media (max-width: 480px) {
  body {
    font-size: 12px;
  }
}

Building a Responsive Navigation Menu:

Example: Responsive Navigation Menu

<nav class="navbar">
  <div class="logo">Brand</div>
  <ul class="nav-links">
    <li><a href="#">Home</a></li>
    <li><a href="#">About</a></li>
    <li><a href="#">Contact</a></li>
  </ul>
</nav>

/* CSS */
.navbar {
  display: flex;
  justify-content: space-between;
  align-items: center;
  padding: 1rem;
  background-color: #333;
  color: #fff;
}

.nav-links {
  display: flex;
  list-style: none;
}

.nav-links li a {
  color: #fff;
  text-decoration: none;
  margin: 0 1rem;
}

@media (max-width: 768px) {
  .nav-links {
    flex-direction: column;
    display: none;
  }

  .nav-links.active {
    display: flex;
  }
}
