Div and background repeat

<style>
#bottombar{
background-color: #0ff000;
position:fixed;
top:92%;
left:0;
width:100%;
z-index:10;
}
#topbar {
background-color: #0ff000;
position:fixed;
bottom:93%;
top:0;
left:5px;
width:100%;
z-index:10;
}
#loading {
position:fixed;
top:50%;
left:25%;
width:100%;
z-index:10;
}

</style>
<div id="topbar"><img align="middle" src="top.jpg" /></div>
<div id="bottombar"><img align="middle" src="bottom.jpg"/></div>
<div id="loading"><img align="middle" src="loading.gif"></div>

Right now I have the above to create a bar at the top and a bar at the bottom of the screen. However my bar currently is a jpg that is 400px long and doesnt go across the top from left to right fully on all screens.

What I want instead is a 1px jpg that is repeated in the x direction across the screen at the top and bottom of the screen.

How owuld I go about this using divs. I've tried the usual backround image and background repeat code but it doesnt seem to work.

HELP!

Hello HIPPY,
Right now your images are not background images so you would not be able to repeat them.

Try one like this instead -
#bottombar{
background: #0ff000 url(bottom.jpg) repeat-x;
position:fixed;
top:92%;
left:0;
width:100%;
z-index:10;
}

and
<div id="bottombar"></div>

I tried that, nothing shows up at all.

You'd need to set some height values in CSS for your empty divs!
