Changing background for each header box

[CyberAlien]

If you are trying to set different background depending on what forum is shown check $vbulletin->GPC['forumid'] like this:

<if condition="!$vbulletin->GPC['forumid']">
   default background
<else /><if condition="$vbulletin->GPC['forumid'] == 1">
   background for forum 1
<else /><if condition="$vbulletin->GPC['forumid'] == 2">
  background for forum 2
</if></if></if>
