I have been playing around with the interactions. But I cant seem to get an element to “slide in” when the user have scrolled say 400px down the page. It’s a fixed element that should slide in.
You can use another element as a trigger for your fixed element to scroll in.
Place an element 400px down the page, like a 0px height section. Assign a OnScroll interaction to it and make it “Affect another element”. Target your fix element. Then OnScroll Out, make your fixed element appear.
I often use dummy (invisible) elements just as triggers for onscroll interactions. It’s much easier to get exactly what you want, especially in your case
