This is a bit harder to achieve than it may seem at first glance, and center tag won't really work. Please consider this code:
<html >
<head>
<title>???</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<style type="text/css"><!--
.center {
margin-top:10px;
margin-left:auto;
margin-right:auto;
text-align:center;
border:solid 1px black;
width:828px;
height:20px;}
--></style>
</head>
<body>
<div class="center">It will work for any inner HTML you want to place here...</div>
</body>
</html>
Got the idea?
