Take a look at this.

The following CSS has been used:

Code:
body {
	background-color: #074E78;
	font-family: Geneva, Arial, Helvetica, sans-serif;
}

#wrapper {
	width: 750px;
	margin: auto;
	border: 1px solid #FFFFFF;
}

#header {
	background-color: #990000;
	height: 100px;
}

#nav {
	background-color: #009900;
	border-top: 1px solid #FFFFFF;
	border-bottom: 1px solid #FFFFFF;
	height: 20px;
}

#content {
	background-color: #29395f;
	height: 300px;
}

#left {
	float: left;
	position: relative;
	top: 5px;
	width: 510px;
}

#right {
	float: right;
	position: relative;
	top: 5px;
	width: 210px;
}

.boxhead {
	background-color: #990000;
	border: 1px solid #000000;
	padding: 2px;
	font-size: 12px;
	color: #FFFFFF;
	font-weight: bold;
	width: 100%;
}

#footer {
	background-color: #172353;
	border-top: 1px solid #FFFFFF;
	padding: 2px;
	font-size: 10px;
	color: #FFFFFF;
	vertical-align: middle;
}
I'm clueless as to why on the right hand side there is a 5px overlap. Any ideas?
