iPad ignoring padding

Hello everyone

I have a general question:
I am building a website where I work a lot with with absolute and relative positioning.
At the desktop everything works fine, but at the iPad - even on the width which is still the desktop break point - it makes what it wants and random stuff while when checking in the browser with the ipad screensize (firefox), everthing is still perfect.

Do u know how to fix that?
