Overlay and title pop-up on hover, code for 7.0

Site URL: https://www.partnersincrime.co/

Hi, 

I've been using this code for a slightly grey overlay and text pop-upp on hover. However, I need the text to be smaller in mobile view, because right now its cut off in the edges and you can't read the full titles. Anyone who knows what I could add for that purpose?
