responsive-design Banner sections not responding well on mobile

Site URL: https://nevernotcreative.org/podcast/creativity-and-football

Hi there,
Just got to a good place with a feature page for my site. Really happy with how desktop is working, but I just seem to always have issues with 'Banners' when using index pages.
I use the banners in this case to add quotes from a podcast series I've created.

Is there a way to make these sections have a minimum width instead of minimum height or do I need to add custom css?

Any help would be greatly appreciated!!

Do you still need help?
