Style of the first post depending on the forum
 

How do I get the style of the first post is different depending on the forum that access, for example, based on postbit_legacy I created a style for the forum, tutorials, and I want the first post in the forum of tutorials rather than show the postbit_legacy that to show the postbit_tutorials, equal here in vBulletin.org as I do that? And how do I change the buttons depending on the forum, the forum example of new mod changes appear in the new tutorial tutorials and so on, how?
