CSS dilemma. Please help a code novice

Problem page: http://danielhaddon.co/showcase/

I’m using Animo theme. When I squish the screen width in the images aren’t responding correctly. I thought it was something to do with a min height in the responsive CSS but I can’t find what is causing it. Does anybody have any ideas?

I’ve also been trying to compare the code to Animo’s demo page but I am lost in a world so unfamiliar to me: http://preview.themeforest.net/item/animo-creative-clean-multipurpose-wordpress-theme/full_screen_preview/16019051?_ga=2.226904861.1806730144.1499641618-868854663.1499641618

Please help :slight_smile:
