Alternating Row colors in Postbit

[n00belit3]

Yes i know this has been asked many times before but as i searched vbulletin .com/org all i could find were modfications for vb2 or for forum display or showthread, none for vb3 postbit.

In order to show alternating row colors in postbit i know i have to replace the alt1 and alt2 class with a conditional but dont know what it is, i imagine its something like this

PHP Code:

<if condition="$forum['threadid'] % 2 == 0">class="alt2"<else />class="alt1"</if> 


Any help would be appreciated thnx.
