Cant remove space between Header and Menu Nav bar - css

Question

I for whatever reason cannot get rid of the gap between my header and the nav bar menu. I've tried every adjustment of padding/margins I can think of to either push it up or move the bar, but it just does funky stuff with the menu or pushes other content up. I need some help.
and the code
#header_wrap {
width:100%;
height:144px;
text-align: center;
}
#header {
width:980px;
margin:0 auto;
}
#preloadedImages
{
width: 0px;
height: 0px;
display: none;
background-image:url(Logo/logo14hover.gif);
}
.site_logo {
float:left;
width:302px;
height:144px;
background:url(Logo/logo14.gif) no-repeat;
}
.site_logo:hover {
float:left;
width:302px;
height:144px;
background:url(Logo/logo14hover.gif) no-repeat;
}
.headerpic {
float:left;
width:678px;
height:144px;
background:url(Images/headerpic.gif) no-repeat;
}
#menu_wrap {
position:relative;
z-index:2;
text-align:center;
width:100%;
padding: 0px 0px;
}
#menu {
position:relative;
z-index:2;
width:1000px;
text-align:center;
margin:0 auto;
height:61px;
padding: 0px 0px;
}

Answer 1

Simply remove the default margin for your main ul (the direct descendant of nav)
Select it using the following CSS, or giving that specific ul a class or id (this way you target only the ul causing you trouble).
nav > ul {margin: 0}
I stuck it into the top of your fiddle, and updated it here
I realise this has now been answered because I took way too long formatting this, but I'd just like to point out that it has nothing to do with the box-shadow which has no impact on positioning.

Answer 2

The ul default margin is responsible for this space. Try setting margin-top:0 to nav ul. Demo: http://jsfiddle.net/xtsAx/8/

Answer 3

for me the error was because i used dream weaver to edit my code.
this give me a hiccup by adding default headers.
when i removed those headers and just gave<html> <head>...<?php>....?> .... </html> it worked perfect.
always remove html tags and header by dream weaver.
**Update: I had the same error again in Firefox so i applied
*{
margin:0;
padding:0;
}
And hence got rid of it completely now.
