Pardon hocam oraya dögüyü koymamışım , döngülü hali budur ve alt alta sıralıyorum bu şekilde.Ama sizin verdiğiniz div leri entegre edemedim.

<style type="text/css">
<!--
body {
	background-repeat: no-repeat;
}
.style1 {
	font-family: Arial, Helvetica, sans-serif;
	font-weight: bold;
}
.style2 {font-family: "Times New Roman", Times, serif}
.style3 {font-family: Verdana, Arial, Helvetica, sans-serif}

}

div.tab{width:100%; float:left;}
div.tab a{width:33%; float:left; color:black;}
-->
</style>
<?php
