Hello!
I have problem with xampp and basic boostrap theme (and all html themes) i am developing/reviewing. They scale upwards multiple times. When my normal screen width for website is 1263px, same theme is, in xampp, 1896,4px wide. How to fix this difference?

You cannot fix that in Xampp, Xampp does not know anything about screens. The problem must be somewhere else.
