I'm no programmer, and I don't want to mess anything up on the front end by changing things on the blog, so I'm being really careful with what I do.
As the title states, my current problem is the featured image. It looks fine on desktop, but terrible on mobile. I've tried adding a mobile featured image plugin, but it doesn't seem to be working. Any help with a quick fix would be much appreciated.
