Mobile view not showing footer properly

When I look at my website on a desktop, the footer displays all my widgets properly. However, when I’m in mobile view, it displays everything one at a time going down vertically. I have an Instagram widget that displays a preview of 3 of my most recent posts. On the desktop it’s just a small portion of the footer, but on mobile, one IG photo takes up the entire screen, so when scrolling, it’s like they’re seeing 3 full-sized photos before getting to see the next widget.
