been working on my website for last couple of days- and for some reason everything scales differently based on wheather or not i use the www prefix on my webpage. What is causing this and how is it even possible if its the same file? this never happened with my old page setup
My bet is that you have accidentally changed the zoom level in your browser, and the zoom setting is saved per domain.
domain.com are treated as different sites internally in your browser.
Check out the zoom level settings and try to reset them.
