thank you very much akapowl. i tried now for a long time, to combine the two things, not getting anyware. not even sure if its not a css problem now. scrolltrigger crates now two pin-spacers, but they dont seem to do what they are supposed to do. as the horizontal sections are just covering them up.
i have now tried to create my first codepen... https://codepen.io/patrickroppel/pen/zYEvPbY
