css help needed for main/center section of shop

Hi there, I'm trying to rebuild my shop on v151 switching from 1.0.3.2

I've updated the style sheets, but no matter what I do, I can't seem to get the center part of the shop be the correct color.
I'm trying to get it to be html color as noted below:

#mainWrapper {
background-color: #ededcd;
text-align: left;
width: 100%;
vertical-align: top;
}

You can see my workspace here:

the shop I'm trying to reproduce is here:
http://spritelygoods.com/index.php?main_page=down_for_maintenance

I've compared the CSS files for both the old and new shops and cannot find the discrepancy.

Any insight anyone might have would be appreciated!
Thanks
Stephanie

Try changing color here

#headerWrapper, #contentMainWrapper, #logoWrapper, #cartBoxListWrapper, #ezPageBoxList, #cartBoxListWrapper ul, #ezPageBoxList ul, #mainWrapper, #popupAdditionalImage, #popupImage {
	background-color: #edf3e6;
	margin: 0em;
	padding: 0em;

thank you Kobra,
Isolating out the #contentMainWrapper and #mainWrapper has done the trick!
