   MyFloBoard, the way in.

   The parallax is sticky scenes rather than scroll-jacking. Each section is
   several viewports tall and holds one full-height panel pinned to the top of
   it; as the section passes, its layers are translated at different rates. The
   depth reads the same as a hijacked scroll and the page still scrolls the way
   every other page does, so a keyboard, a scrollbar drag and Find in page all
   keep working. That last part is not a small thing to give up for an effect.
