Code: Select all
<html>
<head>
<link ref="style.css" rel="stylesheet" type="text/css" >
</head>
<body>
<table border="2" cellpadding="0" cellspacing="0">
<table border="0">
<tr>
<th>CollegeName/UniversityName </th>
<th>Courses </th>
<th>District</th>
<th>Location</th>
<th>Pin Code</th>
<th>STD-Code</th>
<th>Phone1</th>
<th>Phone2</th>
<th>Phone3</th>
<th>FaxNo.</th>
<th>Email-Address</th>
<th>WebPage</th>
</tr>
