[uhim]

hi guys!
what shoukd I do to help for IE to see negative margine?
I have a source :

---------
<td class="head_link_bg" valign="top">
<table cellspacing="0" cellpadding="0">
<tr>
<td>
<div id="full1"><img src="img/head_link_bg_full1.gif" alt="" /></div>
</td>
</tr>
</table>
<table cellpadding="0" cellspacing="0" border="0" class="link_table">
<tr align="center">
<td><a href="#"><img src="img/link_home.jpg" id="link_home" alt="" /></a></td>
<td><a href="#"><img src="img/link_map.jpg" id="link_map" alt="" /></a></td>
<td><a href="#"><img src="img/link_mail.jpg" id="link_mail" alt="" /></a></td>
<td><a href="#"><img src="img/link_search.gif" id="link_search" alt="" /></a></td>
</tr>
</table>
</td>
-----------------------------------------------------
css
---
#full1
{
margin-top:-5px;
width: 136px;
height: 68px;
z-index:1;
}
TABLE.link_table
{
height:25px;
}

In Mozilla I can see everything right. But in IE6 negative margin does not work.
Does somebody know any cheats for IE?
Thanks.

When I tested your code, it moved the image up by 5 pixels properly in both FireFox and IE6. I'm not sure what the problem would be for you. Perhaps you can create a simple test page that has this problem in it.
