Is there a program/script...

[Deimos]

Just wondering, but does anyone know if there's a program or script which lets you build/create a VB compatible style sheet?

So for instance, you'd put in your own colour codes and click Generate or Preview and it'd churn out a CSS file you could import into Vbulletin's style system

No sorry, there's no such script.
