Supply Theme Margins

[virginiajoy]

Hi!

I'm trying to change the margins of my page content in the supply theme.  I recently added a photo gallery widget but the left and right margins are huge, I want to make them smaller but I'm not sure where I need to edit the code. I've found a lot of things that seem to work for other themes but not the supply theme. 

The content of my shop page is in line with the header, and I'd like to change the margins on another page to match.  I've attached pictures too. Thank you!
