One external css for two styles problem

[Madamko]

Hello,

I have a little problem with styling my vbulletin forum.

I have 2 different styles. Both works perfectly. I have added new twitter widget to my web and now I am facing a problem with styling it.

I found a way to change css style of this widget, but I have only one external css file. It means, that BOTH styles uses same css for this widget. This doesn't look good.

Is there any way to check (within this external css file) which style is user currently using and conditionaly change something in css?

Something like getting the style id and checking in css (I believe I can use php) if it is first style or second.

Would really appreciate any help.
Thanks in advance.
