Problem with z-index?

So the site looks fine initially but when I scroll down and then back up the static footer covers the banner section instead of being behind it.

I tried changing the z-index of the banner, but that didn’t seem to work.

Any thoughts on what I’m missing, don’t understand or doing wrong?

Hello fellow Clevelander! Did you try removing the z-index from the footer?
