There are only 2 files, their contents are displayed below. If someone can provide a Standards Compliant solution then I'd be grateful.
I'm not in a rush so take your time, I'll put the sitemap in ajax later hence the noscript list.
Code:
@media screen
{
	html, html *
	{
		margin: 0px;
		outline: none;
		padding: 0px
	}
	ul
	{
		padding: 5px;
		padding-left: 20px
	}
	a, label, input, button
	{
		border-width: thin;
		display: inline-block;
		font-size: medium
	}
	html
	{
		overflow: auto
	}
	body
	{
		position: relative
	}
	/* Navigation */
	/* - Default as List */
	#n
	{
		position: absolute;
		top: 0px;
		left: 0px
	}
	/* - Not IE6 or below */
	#nav > #n { position: static }
	#n > ul
	{
		display: block;
		font-size: 2pt;
		text-align: justify
	}
	#n > ul *
	{
		font-size: medium
	}
	#n > ul a
	{
		text-decoration: none
	}
	#n > ul > li
	{
		position: relative;
		display: inline-block;
		list-style: none;
		white-space: nowrap
	}
	#n > ul > li.last
	{
		font-size: 2pt;
		width: 100%
	}
	#ie7 #n > ul > li
	{
		/* Workaround */
		display: inline
	}
	#ie7 #n > ul
	{
		
	}
	#n > ul ul
	{
		background: #fff;
		border: #000 solid thin;
		border-radius: 5px;
		display: none;
		position: absolute;
		top: 5px;
		left: 90%
	}
	#n > ul > li > ul
	{
		top: 90%;
		left: 5px
	}
	#n > ul li:hover > ul
	{
		display: block
	}
	#search > form { display: inline-block }
}
