B4J Question CSS: Switching "sub-classes"?

[LWGShane]

I'm wanting to use this really awesome Bootstrap theme with my programs. But I am wondering on how to switch between "sub-classes". For example, changing the Button from "default" to ".primary".

Thanks!

You can add classes with the StyleClasses property:

Button1.StyleClasses.Add("primary")

It returns a List so you can also clear it.
