Simple CSS question

Hi
I am playing with some simple HTMl and CSS (see below) and have a problem with it.
If you open the below HTML in Firefox above the nav bar there is a row or purple. I can't seem to lift the nav and the columns to cover this. Can anyone help me please? I'm sure its a simple tweak of the HTML or CSS but can't figure it out. Thank you!

<html>
<head>
<style>
body,
html {
margin:0;
padding:0;
color:#000;
background:#a7a09a;
}
#wrap {
width:500px;
margin:0 auto;
background:#99c;
}
#header {
background:#ddd;
}
#nav {
background:#c99;
}
#nav ul {
margin:0;
padding:0;
list-style:none;
}
#nav li {
display:inline;
margin:0;
padding:0;
}
#main {
float:left;
width:200px;
background:#9c9;
}
#sidebar {
float:right;
width:100px;
background:#99c;
}
#footer {
clear:both;
background:#cc9;
}
</style>
</head>
<body>
<div id="wrap">
<div id="header"><h1>Heading</h1></div>
<div id="nav">
<ul>
<li><a href="#">Option 1</a></li>
<li><a href="#">Option 2</a></li>
</ul>
</div>
<div id="main">
<h2>Col 1</h2>
<p>Lorem ipsum dolor sit amet, con adipiselit...</p>
</div>
<div id="sidebar">
<h2>Col 2</h2>
<p>Lorem ipsum dolor sit amet, con adipis elit...</p>
<ul>
<li><a href="#">Link 1</a></li>
<li><a href="#">Link 2</a></li>
</ul>
</div>
<div id="footer">
<p>Footer</p>
</div>
</div>
</body>
</html>

</html>

Change this:
#header {
background:#ddd;
}

To this:
#header {
background:#ddd;
border:2px solid red;
}


Some comments:

1. Instead of typing code as you did, give us a URL.

2. Use a doctype so that you can validate your html at
http://validator.w3.org/ . Also validate your CSS at
http://jigsaw.w3.org/css-validator/

3. Indent your html correctly. It is much easier to read.

That's just 3 for starters. Enough for now.

You're best advised to ask CSS questions at c.i.w.a.stylesheets .

An easy way to confirm if a problem is due to collapsing margins is to
include this temporarily in your stylesheet:
* {margin:0 !important;}
To only accomplish what you ask, add this:
h1 {margin-bottom:0;}
but to also move the whole #wrap to the top of the viewport, do the same
to margin-top or:
h1 {margin:0;}

Not quite as simple as it could be (you are not likely needing a
div to wrap the h1, nor another to wrap the ul. You can id or
class and style the h1 and ul directly) but essentially your
problem can be solved by over-riding default bottom margins and
top margins to a couple of elements.

3. Indent your html correctly. It is much easier to read.

If posted on usenet, there is an argument for not indenting it.
