Style ID conditions?

[DPSR]

Hello friends,

I need a little help, i am using two styles on my site and also using custom forum status icon hack.

So, as i have two styles ..i want to apply custom forum status icon hack on both designs. I think it is possible with condtions like:

<if condition style id:1> use status icon set 1

else use status icon set 2

Can you tell me exact condition for styles?

Thanks all for your help
