is topper-menu float-top a class id ?
how changing float-right to float-top fixed that issue in IE is beyond me ..
class id's can not contain spaces as far as i know .
there is no float top in style
only float right or left .
if that is style . then is wrong way to write ..
it should be
example .
<div class="topper-menu" style="float:right;"></div>
im just kinda curious ..



thanks for your help i changed
