How to add favicon to your website
To add a favicon to your website, either save your favicon image to the root directory of your webserver, or create a folder in the root directory called images, and save your favicon image in this folder. A common name for a favicon image is "favicon.ico". Next, add a <link> element to your "index.html" file, after the <title> element, like this:
Example
<!DOCTYPE html>
<html>
<head>
<title>My Page Title</title>
<link rel="icon"
type="image/x-icon"
href="/images/favicon.ico"> </head>
<body>
<h1>This is a Heading</h1>
<p>This is a paragraph.</p>
</body>
</html>
<html>
<head>
<title>My Page Title</title>
<link rel="icon"
type="image/x-icon"
href="/images/favicon.ico"> </head>
<body>
<h1>This is a Heading</h1>
<p>This is a paragraph.</p>
</body>
</html>
Now, save the "index.html" file and reload it in your browser. Your browser tab should now display your favicon image to the left of the page title.
