Banner Slideshow Mobile Resize

Need help with banner slideshow resizing on mobile. I have a slideshow on my home page that scrolls through 3 images, each with a short title over top and a button with link to their respective pages. 

With no code, the mobile view is too tall and crops off too much of the image.

I've tried some code but the titles keep getting cut off and the images still too cropped.

I'm looking for some code to resize the image, text, and button all together (Similar to this site: https://www.lechase.com/)

This is literally my last step before going live. Any ideas?
