Footers are essential components of web design, providing users with crucial information and navigation options. In this article, we’ll explore how to create a fixed footer using CSS, dive into the semantics of the <footer>
tag, and discuss tips, browser support, and best practices.
Creating a Fixed Footer with CSS
A fixed footer remains at the bottom of the viewport regardless of how much content is on the page. This ensures that important information, such as contact details or links, is always visible to users. Here’s a basic example of how to create a fixed footer using CSS:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Fixed Footer Example</title>
<style>
.footer {
position: fixed;
left: 0;
bottom: 0;
width: 100%;
background-color: red;
color: white;
text-align: center;
padding: 10px;
box-shadow: 0 -2px 5px rgba(0,0,0,0.3);
}
</style>
</head>
<body>
<!-- Main content of the page -->
<div class="footer">
<p>Footer</p>
</div>
</body>
</html>

Definition and Usage of the <footer>
Tag
The <footer>
tag is part of HTML5 and is used to define the footer for a document or a section. It helps in structuring your HTML document semantically, making it easier for browsers and screen readers to understand the content.
Common Uses for <footer>

A single HTML document can include multiple <footer>
