Footer and Safari issues

Hello,

I am not sure what I am doing wrong here but I seem to get problems with safari.

1. My footer does not seem to slide up on the safari browser. (Desktop)

2. I have a slider and added 2 buttons (from the button menu) and they don’t work correctly in safari at all. I can’t click and they don’t seem to stay in the same location when viewing on mobile safari.

Is there something I am missing here? Chrome seems to work all fine.
