@elegantseagulls ok, I see that part that toggles the class when the .box-3 class is triggered, but what I want to try to do is have the purple section hold, while the user scrolls and active class is toggled between different divs, then at the end continue on. It would kind of function like a slider, so imagine you scroll to the purple section, there is an image and text slide, as the user scrolls the active class is passed to the next "slide" until the end, then it continues on.
