7.3 Homework/Practice

Build a sidebar layout using float. Apply relative positioning to the sidebar and absolute positioning to a menu button inside the sidebar.

Build a Sidebar Layout Using Float

  1. Step 1:

    • Create an HTML structure for a page with a header, sidebar, main content area, and footer. Use float to position the sidebar on the left and the content on the right.

      <!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Sidebar Layout</title>
  <style>
    body {
      font-family: Arial, sans-serif;
    }
    header, footer {
      background-color: #333;
      color: white;
      text-align: center;
      padding: 10px;
    }
    .sidebar {
      float: left;
      width: 25%;
      background-color: #f4f4f4;
      padding: 10px;
      box-sizing: border-box;
    }
    .content {
      float: left;
      width: 70%;
      padding: 10px;
      box-sizing: border-box;
      background-color: #ddd;
    }
    footer {
      clear: both;
      background-color: #333;
      color: white;
      text-align: center;
      padding: 10px;
    }
  </style>
</head>
<body>
  <header>
    <h1>My Sidebar Layout</h1>
  </header>
  <div class="sidebar">
    <h2>Sidebar</h2>
    <p>This is the sidebar content.</p>
  </div>
  <div class="content">
    <h2>Main Content</h2>
    <p>This is the main content area.</p>
  </div>
  <footer>
    <p>Footer Content</p>
  </footer>
</body>
</html>

  2. Step 2:

    • Apply Relative Positioning: Apply relative positioning to the sidebar to move it slightly to the right.

      .sidebar {
  position: relative;
  left: 10px;
}

  3. Step 3:

    • Absolute Positioning for Menu Button: Add a button inside the sidebar and use absolute positioning to place it at the bottom-right corner of the sidebar:

      <button style="position: absolute; bottom: 10px; right: 10px;">Menu</button>

  4. Step 4:

    • Test Responsiveness: Adjust the layout for smaller screens using media queries to ensure the sidebar becomes a full-width block at smaller sizes.
