possible to provide a liquid version

I have no plans to provide a "fluid" version of Barron. However, here's what you can do to make it so:

In style.css change to the following:

#container
{
	margin:0 auto;
	width:100%;
}

#nav 
{
	height:100%;
	margin: 0;
	padding:5px 10px 5px 0;
	position: absolute;
	right: 0;
}

#content
{
	display:inline;
	float:left;
	margin:20px 0 20px 10px;
	overflow:hidden;
	width:78%;
}

#sidebarWrapper
{
	background:transparent url('images/sidebar_bottom.jpg') no-repeat scroll left bottom;
	display:inline;
	float:right;
	margin-top:20px;
	width:20%;
}
