Color body without messing up wrap?

https://www.spygolfer.com

I want to change the body and header color to black, but when I do it messes up the dividers on each side, which I believe is part of the wrap.

I put this in the header and wrap:

background-color: #000000 !important;
background-image: none !important;

But it also makes the rounded edges that I have square. Like around my sidebar and posts. Anyone know how to just fill the body and head background with black, without messing anything up?

Thanks.

Here the top of my stylesheet:

body {
	text-align:center;
	font:62.5%/1.42 "trebuchet ms",arial,helvetica,sans-serif;
	min-width:994px;

}
#page {
	width:994px;
	margin:0 auto 11px;
	padding:0 0 18px;
	font-size:1.2em;
	text-align:left;

}
#header {
	width:100%;

}
#wrap {
	width:100%;
	clear:both;
	padding:34px 0 0;

}
#content {
	width:655px;
	margin:0 313px 0 26px;
	float:left;
	display:inline;
}
.home #content {
	width:518px;
	margin:0 450px 0 26px;
}
.sidebars {
	float:left;
	display:inline;
}
#sidebarOne {
	width:268px;
	margin:0 0 0 -294px;
}
.home #sidebarOne {
	width:405px;
	margin:0 0 0 -431px;
}
#footer {
	width:100%;
	clear:both;
	overflow:hidden;
	text-align:center;
	font-size:1.2em;
	padding:20px 0;
}
