Awkward problem needs solving :S

At the moment I am in the middle of designing a blog template, but I've ran into a problem and cannot continue until this problem is solved.


Problem:
My drop down menu is not working properly in internet explorer and firefox, BUT works fine in Chrome and Opera. Check it out yourself...

Template Link( hover over top buttons ):
click here

Style sheet:
Click here


The testing page for the drop down:

<link href="stylesheet.css" rel="stylesheet">
<style type="text/css">
.nd_wrap{
	width:1000px;
	height:auto;
}
.ndtut{
	position:relative;
	width:200px;
	height:auto;
	padding-top:5px;
	padding-left:10px;
	padding-right:10px;
	padding-bottom:5px;
	z-index:2;
	background:url(images/qnbg.jpg);
	text-align:left;
	float:right;
}
</style>
<script language="JavaScript">
function setVisibility(id, visibility) {
document.getElementById(id).style.display = visibility;
}
</script>
<a class="ntut" href="#" on onMouseOver="setVisibility('drop1', 'inline');" onMouseOut="setVisibility('drop1', 'none');" ></a>
<div class="nd_wrap">
	<div id="drop1" class="ndtut" onMouseOver="setVisibility('drop1', 'inline');" onMouseOut="setVisibility('drop1', 'none');">
	   <div>link1</div>
	   <div>link1</div>
	   <div>link1</div>
	</div>
</div>
<!--onMouseOver="setVisibility('drop1', 'inline');" onMouseOut="setVisibility('drop1', 'none');"-->

So forum, how can I make this work in both internet explorer and firefox?

 

Personally I would only use Position: relative; on the dropdowns.

However a quick fix could be

.ndtut{
position:fixed;
width:200px;
height:auto;
padding-top:5px;
padding-left:10px;
padding-right:10px;
padding-bottom:5px;
z-index:3;
background:url(images/qnbg.jpg);
text-align:left;
margin-left:-120px;
margin-top:50px;
display: none;
}

Bold for right value for FF.
You then can use conditional comments for IE and FF

NB. I have taken ndtut as an example

 

Problem solved I used you code +

		<!--[if IE]>
			<link rel="stylesheet" type="text/css" href="ie_only.css" media="all" />
		<![endif]-->

Glad I could help
