I used this like above:

/*wrappers - page or section containers*/
#mainWrapper {
background-color: #000000;
background-image: url('../images/space011.jpg');
text-align: left;
width: 100%;
vertical-align: top;
}

That changed my backgroung inside the main area but I want the main background not the background behind the store etc... if that makes sense.

??

Thanks
