XF 1.4 looking to add a background to the Main forum page only!

[oO5 Dynasty]

I think i have this part wrong.
body.forum_list

body.forum_list {
    background-image: url("http://i.imgur.com/cjPnOhL.jpg");
    background-attachment: fixed !important;
     background-size: cover !important;
    background-color: #000;
    -webkit-background-size: cover;
      -moz-background-size: cover;
      -o-background-size: cover;
      background-size: cover;over;
  
}

Because this one actually works
body.node95 when i add the background to a page node.

body.node95 {
    background-image: url("http://i.imgur.com/cjPnOhL.jpg");
    background-attachment: fixed !important;
     background-size: cover !important;
    background-color: #000;
    -webkit-background-size: cover;
      -moz-background-size: cover;
      -o-background-size: cover;
      background-size: cover;over;
  
}
