{width:90%; min-width:400px;} includes IE5+ and IE6
this is the standards compliant way that I have found to emulate true min-width in IE which just requires an extra outer container.
this div has a min-width of 400px and a width of 90%. You can set the width as any percentage and the min-width as a px or em value.
