I have been playing around with my css lately and boy - theres so many things yo can do. :D
I could not determine if this was a css issue or a SMF issue. But this is whats current my hover link.
a:hover {border-bottom: 1px dashed #CDCDB4; color: #B42000;text-decoration: none;}
Anyway I do not want the dashes to appear on the on the bbc. Is there a way to disable it on images?
Perhaps you can wrap the BBC in a new <div> with a different class, example "noborder". Then add:
.noborder a:hover { border: 0px; }
If you are using the [img][/img] tags you can try to add the border: style to remove the dashes to the class assign to img tag (class="bbc_img")
