CSS browser fixed width

In web development, you often need to control the width of the browser window and fix it to a specific width. This requirement is very common in designing responsive web pages and fixed layouts. This article will detail how to use CSS to achieve a fixed browser width.

Setting a Fixed Width with CSS

In CSS, we can control the width of an element by setting the width property. To achieve a fixed browser width, we need to set a fixed width for the body or other container element.

Here is a simple example code that demonstrates how to use CSS to fix the browser width to 800px:

<!DOCTYPE html> 
<html Tutorial">html lang="en"> 
<head> 
<meta charset="UTF-8"> 
<meta name="viewport" content="width=device-width, initial-scale=1.0"> 
<title>Fixed Width Browser</title> 
<style> 
body { 
width: 800px; 
margin: 0 auto; 
background-color: #f2f2f2; 
padding: 20px; 
} 
.content { 
background-color: #fff; 
padding: 20px; 
border: 1px solid #ccc; 
} 
</style> 
</head> 
<body> 
<div class="content"> 
<h1>Hello, Fixed Width Browser!</h1> 
<p>This is a demo of setting fixed width for browser window.</p> </div>

</body>

</html>

In the above code example, we set the width of the body element to 800px, fixing the entire page content to a fixed width of 800px. margin: 0 auto; is used to horizontally center the page.

Running Results

If you save the above code example as an HTML file and open it in a browser, you will see that the page content is constrained to a fixed width of 800px, as shown below:
