Debut Theme: Resizing Slideshow in Mobile View So Text & Button Doesn't Lay Over Slideshow Image

[gbanks789]

I am trying to figure out how to resize my slideshow in mobile view so that the button and text are not placed over the image and the image is not zoomed all the way in. 

This is what mine looks like now in mobile view.

This is what I want it to look like in mobile view.

Can someone please help? I've been looking everywhere and cannot seem to find an answer to this.
