[paulmkeogh]

Hi all.

Given;

	<h:body styleClass="body">
		<rich:panel styleClass="header">
		Header
		</rich:panel>
		<rich:panel  styleClass="bodypanel">
			Bodypanel
		</rich:panel>
		<rich:panel styleClass="footer">
			Footer
		</rich:panel>
	</h:body>

and the CSS contains 100% height for html and body, what do I put into the header,bodypanel and footer styleClass to get %heights of 10,80 and 10 respectively ?
