Padding on side of page

Site URL: https://www.kisskissem.com/

Hello! I have just very knocked up a temporary site for myself as my subscription renewal was coming up and I wanted to switch my very old website over to 7.1. I'm having a little trouble though with the padding on the side of the main body content and footer. I want them both to align and be set to the same width as the header, but I can't figure out how to do that... I've set the width of the section to the largest and tried changing the spacing in Site Styles, but it doesn't seem to make a difference. It does, however line up on the mobile site, just not on the desktop version. Any thoughts?

Thank you!

Hi,

It looks like you figured it out?
