I stumbled upon this piece of code :

Code:
#main ul a.selected {
  margin-bottom:0;
  color:#000;
  background:snow;
  border-bottom:1px solid snow;
  cursor:default;
  }
#main div {
  padding:10px 10px 8px 10px;
  *padding-top:3px;
  *margin-top:-15px;
  clear:left;
  background:snow;
  height: 300px ;
}
I know what most of this code does, but I wonder what that asterisks and that snow value do!
Any ideas?
Thank you.
