if i have a banner zone 460x60px and i have a prefix with a 15px of line hight i can see a banner only of 460x45px beacuse 15px are prefix.
I think it's not correct because banner must be 460x60px and prefix 15px must be added for totalt of 460x75px
for example
<div style="heght:15px" id="prefix">Sponsor</div><div>BANNER460x60</div>
how i can fix?
