Different Views in Chrome and Firefox

hi

On this page http://snazzyproductions.com/tickets/ , why are views different in chrome and firefox? I want the words to be below the ‘catalyst’ image, not next to it. How do I fix this? See differences at this link https://www.evernote.com/shard/s28/sh/ce539f8a-ed7b-4d28-a642-7cb9b11dd305/6763325a4db4609e3851f0e201bb483a

kind thanks for your help.
