Main Wrapper

[oxicottin]

Hello, I want to use an image inside my main wrapper. I have this code in my stylesheet:

#mainWrapper {
	background-image: url(../images/burn_paper.gif);
	text-align: left;                                                         
	width: 90%;                                                                          vertical-align: top;  
	border: 1px solid #9a9a9a;

It repeats the image which I dont want... I tried using this code:

#mainWrapper {
	background-image: url(../images/burn_paper.gif);
	background-repeat:no-repeat;
	text-align: left;                                                         
	width: 90%;                                 
	vertical-align: top;  
	border: 1px solid #9a9a9a;

But it just make my image in one corner. My image is 600x800px. What do I need to do to get it to cover the whole main wrapper? I dont want it as the body background image.. Thanks!
