XF 1.2 The best way to add padding the the sides of your forum?


I just started working with 1.2 and would like to have my forum have 90px of padding on each side all the way down the page so everything is nicely aligned. I managed to get most of the elements on the page to have this but it really messes with the responsive design when the page is squished. What do you think is the best way to do this?
