Change side padding - gallery index page

Site URL: https://www.thenaturaldyeworks.com/new-home

Hey, 

Working on a client's site (I'm not a designer as such, just a VA who ends up doing these things). Trying to add some padding either side of these top three images so their outer edges are in line with the logo and the nav bar. Have tried adding all kinds of code, but I'm getting nowhere. It's running on Jaunt. Anyone? 

You may need to use spacer bars as opposed to padding. You should be able to add one to either side and adjust it to move the images inline the nav bar.
