Practical Example: Implementing a Basic Responsive Layout
Here's a simple example of a responsive layout using HTML and CSS:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Responsive Design Example</title>
<style>
body {
font-family: Arial, sans-serif;
margin: 0;
padding: 0;
}
.container {
width: 100%;
max-width: 1200px;
margin: 0 auto;
padding: 20px;
}
.header, .footer {
background-color: #333;
color: #fff;
text-align: center;
padding: 10px 0;
}
.content {
display: flex;
flex-wrap: wrap;
}
.box {
flex: 1 1 300px;
margin: 10px;
padding: 20px;
background-color: #f4f4f4;
border: 1px solid #ddd;
}
</style>
</head>
<body>
<div class="container">
<div class="header">Responsive Design Example</div>
<div class="content">
<div class="box">Box 1</div>
<div class="box">Box 2</div>
<div class="box">Box 3</div>
</div>
<div class="footer">Footer</div>
</div>
</body>
</html>Explanation:
- Viewport Meta Tag: Ensures the page scales correctly on different devices.
- Flexbox: Used to create a flexible layout that adjusts based on screen size.
- Media Queries: Not used in this basic example but are essential for more complex responsive designs.
Exercise: Create a Simple Responsive Page
Task: Modify the above example to include a media query that changes the background color of the .box elements to light blue when the screen width is less than 600px.
Solution:
Feedback and Tips:
- Common Mistake: Forgetting to include the viewport meta tag, which can lead to improper scaling on mobile devices.
- Tip: Test your design on multiple devices and screen sizes to ensure a consistent user experience.
