I have a CSS code with medias:
---------------------
@media TV, screen{
    BODY{
        background-color: green;
        color:red;
    }
}
@media print {
    BODY {
        background-color: white;
        color:black;
    }
}
H2{
}

----------------
in navigator, there are just three lines:
CSS 
   BODY
   BODY
   H2
it would be better to separate media specific rules into a media category:
CSS
  TV, screen
     BODY
  print
     BODY
  H2
different icon for medias (TV, screen line) and CSS rules (H2 line) would also help users orientation
