How can we give different styling for each tabItem in tabsheet.
Like first two tab items in one color, next two in some other color and so on
I don’t think that is really possible right now. Vaadin 7 might bring some improvements with it (

) but for now, you’d have to go and extend the client side of the component and add the possibility to give every tab a distinct style name.
