Site is crashing in different platforms

I am working on Ecommerce website where I have made the site responsive in all the devices like mobile, tab and desktop using media queries. And also I have used vue.js quasar framework for making site responsive. So here in windows platform site is working fine in responsive device But the issue is while I am running the site in other platform like mac or other I am facing an issue Like layouts are braking but the same if I am using in windows platform the site is working exactly fine. So please anyone can tell me what could be the issue.
