CSS help

I am currently editing a template so I can use it for my website, I don’t know much about CSS so I need your help guys.

At this moment the navigation bar is limited till the point where the navigation option is, I would like to extend it to whole length of the page (before the footer starts).

Could you please tell me what I need to do to make this happen?

 

posting your css snippet or site would help me help you

 

Here is the CSS Code

body {
        font-family: tahoma, helvetica, arial, sans-serif;
        font-size: 12px;
        text-align: left;
        background: url(images/page_bg.gif);
    }
    
html, body, #wrapper, h1 {
	margin: 0;
	padding: 0;
}

th, td {
	font-size: 10px;
}

img { border: 0; }

Code (markup):

The CSS being used for the Nav bar is under the tag browse

#browse {
	float: left;
	width: 160px;
	margin: 0;
	padding: 0;
	background: white;
	border-bottom: 2px solid white;
}

#browse dt {
	background: #c80000 url(images/dt_bg.gif) bottom repeat-x;
	color: #fff;
	margin: 2px 2px 1px 2px;
	padding: 6px 0;
	text-align: center;
	font-weight: bold;
}

#browse dd {
	background: #227293;
	border-bottom: 1px solid #659db4;
	padding: 0;
	margin: 0 2px;
}

#browse dd a {
	color: white;
	font-weight: bold;
	text-decoration: none;
	display: block;
	padding: 3px 22px;
}

* html #browse dd {
	padding: 3px 22px;
	padd\ing: 0;
}

* html #browse dd a {
	display: inline;
	di\splay: block;
}

#browse dd a:hover {
	background: #74a7b7;
}

#browse .first {
	padding-top: 10px;
}

#browse .last {
	padding-bottom: 8px;
	border-bottom: 1px solid white;
}

Code (markup):

This is the theme I am planning to use www.freewebsitetemplates.com/preview/onlinemoviestore/

I have changed a few things, the search option isn't there any more along with a couple more changes.

 

#browse {
float: left;
width: 160px;
height:100%
margin: 0;
padding: 0;
background: white;
border-bottom: 2px solid white;
}

I added a height attribute in there. try playing with that and see what happens

 

Thanks Jrd1mra, but it didn't work :

 

add more dd in html *how many u need* for more buttons but i think u need a faux column here.
