extended horizontal nav bar

[ikidunot]

Right now I have a wordpress theme that has a solid black bar for its main navigation at the very top of the site. How would I go as to make it extended across the whole horizontal axis and with an repeated image over it.

my site is www.ravegrounds.com

i want the nav bar to be like www.threadless.com

/* 2.1 Containers & Columns */
#wrapper { background: url() no-repeat center top; }

.col-left { float: left; }
.col-right { float: right; }
.col-full { width: 940px; margin: 0 auto; }

/* 2.2 Navigation */
.nav { z-index:99; margin:0; padding:0; list-style:none; line-height:1; }
.nav a { position:relative; display:block; z-index:100; }
.nav li { float:left; width: auto; }

Hello ikidunot,
Right now you style #top-nav with .col-ful which limits it to being 1000px wide.
Move #top-nav out of #wrapper and remove that class,
like this -

 <div id="top-nav">
		
        <ul class="nav sf-js-enabled">
			            	
	            	            <li class="page_item current_page_item"><a href="http://ravegrounds.com">Home</a></li>
	            <li class="page_item page-item-2"><a href="http://ravegrounds.com/?page_id=2" title="About">About</a></li>
<li class="page_item page-item-3"><a href="http://ravegrounds.com/?page_id=3" title="Forums">Forums</a></li>
	            
           	       <li class="nav-item-right"><a href="http://ravegrounds.com/?feed=rss2"><img src="http://ravegrounds.com/wp-content/themes/Spectrum%20v1.0.2/images/ico-rss.png" alt="RSS Feed"></a></li>   
        </ul><!-- /#nav -->
               
	</div><!-- /#top-nav -->


<div id="wrapper">

	
           
	<div id="header" class="col-full">
 		       
		<div id="logo">

Then make your style.css look like this -

.nav li  { float:left; width: auto; }

#top-nav  { 
width: 100%;
font-size: 12px; 
background: #000; 
overflow: auto;
}
#top-nav a  { line-height: 50px; color: #939497; border-right: 0px solid #414141; padding: 5px 10px; }
#top-nav a:hover, #top-nav li.current_page_item a, #top-nav li.current_page_parent a  { color: #fff; }
#top-nav li ul

When posting code in the forum, please use the code tags, [code][/code] - available with the # button in the post edit window.
This will wrap your code in a scroll box which greatly helps the readability of your post.

That worked perfectly, thank you. I have another question though, in order to get the links back to where they were earlier, which was towards the center of the page, would I have to set absolute positioning for those links?

Give your ul.nav a width and position that. No need for absolute positioning.
Try this -

.nav { 
width: 1000px;
/*z-index:99; this is not doing anything*/
margin:0 auto; 
padding:0; 
list-style:none; 
line-height:1; 
}

Adjust that width to suit.
