I specified a rule for all IE versios, but its not working for some reason.
<!--[if IE]>
<style type="text/css">
#topmenu LI.fisrt {
padding: 5px 5px !important;
font: 13px/43px sans-serif !important;
text-transform: uppercase;
}
</style>
<![endif]-->
From MSDN:
The idea is that IE10 has much better standards support than older IE versions and there should no longer be any need to conditionally target it.
