You're welcome. I might add that that tutorial is deficient in that there is no
doctype specified on the page - without this IE in particular is quite likely to misbehave. You should have a doctype at the very top of your html:
Code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<link href="style.css" rel="stylesheet" type="text/css">
</head>
<body>
<div id="container">
<div id="header">A</div>
<div id="leftnav">B</div>
<div id="rightnav">E</div>
<div id="body">C</div>
<div id="footer">D</div>
</div>
</body>
</html>
