Take a look at
http://www.ecsu.ca first through Internet Explorer, then through FireFox.
In FF, there's a small gap above the main menu.
In IE, there's not.
Here's the code (or you can View --> Source yourself) of the two tables. The first holds the top banner, the second holds the main menu.
<table border="0" width="100%" cellspacing="0" cellpadding="0">
<tr>
<td><img src="image/topbar.bmp"></td>
</tr>
</table>
<table border="0" width="100%" height="25" cellspacing="0" cellpadding="0" bgcolor="#6379BD">
<tr>
<td align="center">
<ul class="menu">
<li class="currloc"><a href="">Home</a></li>
<li><a href="about/">About ECSU</a></li>
<li><a href="froshweek/">Frosh Week</a></li>
<li><a href="services/">Services</a></li>
<li><a href="forums/">Forums</a></li>
<li><a href="clubs/">Clubs</a></li>
<li><a href="photos/">Photos</a></li>
<li><a href="pub/">Blind Duck Pub</a></li>
</ul>
</td>
</tr>
</table>
Anyone know what's going on and why?
