Using CSS background properties, you can set the background of the whole page or of a page element: DIV, paragraph, table, form, etc.

 <style type="text/css"><!--

</head>
<body>
 <div id="idd">Web site: http://CoursesWeb.net</div>
</body>
</html>

Multiple values for background property

The background property allows to add individual background properties (background-color, background-image, background-repeat, background-attachment, background-position) in the same definition, separated by space.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head>
 <title>background-position</title>
 <style type="text/css"><!--
 #idd { background:#f8fbfe url('image.jpg') 50% no-repeat }
 --></style>
</head>
<body>
 <div id="idd">Have a good life.</div>
</body>
</html>
  - Result:
Have a good life.
- When individual properties are left out of the background property, they are set to their default values.
