Scroll to bottom should show footer

I noticed on mobile if I scroll to the bottom of the page, the floating buttons are in the way. It'd be nice if they got "stuck" above the footer area so I can be able to tap the sha link in the footer.

Currently I can't tap or read the footer on mobile. I've only tested on one device, so maybe it works for others.

Note: I was using Mobile Safari, apologies in advance 😆
