@worry This is a black fade-out style that appears at the edges of small screens. Presumably to indicate you can scroll? On the bottom of the screen though it gets stuck at the original position even when you scroll down. So it ends up just awkwardly in the middle of the screen. I can't figure out what CSS is causing it or if it's a browser thing that we should figure out how to override.
