Site looks different on Mac

You are going to be fighting a battle that you really dont want to tackel lol. Anyways, from my experience there is little difference if any. I dont even bother with styles for operating systems. However Mac tends to render -webkit a bit differently sometimes. You will see things like, buttons and inputs styles a bit different.

Using a good CSS reset takes care of this, but must be put in place before design and development take place. Installing a reset no will most likely make the issue worse.

Its covering the text on IE (a little bit), Chrome (completely) on my windows 8 machine. So the issue is bigger than safari/mac

My resolution is 1920 x 1080 on both platforms. New to CSS where to i place a reset to test it and how do i do it?

The typcial CSS reset may work https://meyerweb.com/eric/tools/css/reset/ but that’s also a premium theme; check with the theme author: https://themeforest.net/user/TrueThemes/portfolio?ref=TrueThemes
