HTML provides the structure while CSS controls the styling and layout.

CSS media queries are commonly used to make websites responsive.

Prerequisites

Basic knowledge of HTML and CSS.

A code editor like VS Code.

Step 2: Add HTML Structure

              
            
HTML

            
            <!DOCTYPE html>
<html>
<head>
  <title>Responsive Website</title>
  <link rel="stylesheet" href="style.css">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
</head>
<body>
  <header>
    <h1>My Responsive Website</h1>
  </header>

  <section class="container">
    <div class="box">Box 1</div>
    <div class="box">Box 2</div>
    <div class="box">Box 3</div>
  </section>
</body>
</html>
          

Step 3: Add CSS Styling

              
            
CSS

            
            body {
  font-family: Arial, sans-serif;
  margin: 0;
  padding: 0;
}

header {
  background: #333;
  color: white;
  text-align: center;
  padding: 20px;
}

.container {
  display: flex;
  gap: 20px;
  padding: 20px;
}

.box {
  flex: 1;
  background: lightblue;
  padding: 40px;
  text-align: center;
  font-size: 20px;
}

@media (max-width: 768px) {
  .container {
    flex-direction: column;
  }
}
          

Step 4: Open the Website

Open the index.html file in your browser.

Resize the browser window to see the responsive layout.

Output

              
TEXT

            Desktop: Boxes appear side by side
Mobile: Boxes stack vertically

Detailed Explanation

The Flexbox layout is used to arrange elements horizontally.

The media query changes the layout when the screen width becomes smaller than 768px.

The viewport meta tag ensures proper scaling on mobile devices.

On large screens, all boxes are displayed in a single row.

On smaller devices like smartphones, the boxes automatically stack vertically.
