many thanks mad.
I try it, but its too difficult to use it (perhaps only for me) in the Backend. Now I realize it with the caption option of the carousell. That work. But not perfektly because, I need a caption with a background-color, but 3 diffefent colors, dependent from the slider-picture. Dark picture -> the redaktuer need caption width bright background-color, bright picture then the redakteur needs dark background-color in the caption.
I thinks thats the right way: Add id and class to nodes
