To make a picture into a background image of a web page, you need to use background-image attribute
Here, replace the “Desert.jpg” with the name of your image file which you want to display on your web page.
For example,
<!DOCTYPE html>
<html>
<head>
<title>Example of cite tag</title>
</head>
<body style="background-image:url(Desert.jpg)">
</body>
</html>
