I am building a website where the right half of the site pans layers out of view as you scroll. I am trying to figure out, though, how to only have the layers pan back in when you scroll up. See what I am talking about here: http://topherdigital.webflow.io/ (scroll down the page, then scroll back up - then down again). The first scroll down is what I want the entire experience to look like, then reversed when you scroll back up.
I would like the right half to simply pan back in when you scroll up rather than panning in and out.
