McGuire question: Responsive design

Earlier i had said, if i use % on desktop, then when i go to other devices i can either make that % bigger or I can switch % to Px!

Mc-Master answered with: personally, i would get "frustrated by having to change formats and measurements everywhere between device widths”

What padding, margin, PX / % - based solution do you apply?\ to avoid changing measurements constantly? Whats the process, so you dont have to change stuff around across devices
