how to implement more than one background?

[Tiemo Hollmann TB]

Hi,

I would like to have a stack with x cards. Some of them should have assigned
background a, like header informations, some cards should have assigned
background b, like record informations.

Is there any "assignment" of a certain background to a card which I have
overlooked up to now, or do I have to "assign" the different backgrounds by
showing and hiding the wanted background for each card?

Thanks for your ideas
