Padding on sides of content

Hello, I noticed this issue while viewing my site on mobile devices, then I tried to view the site on a computer in a smaller window and the same issue occurred. When there isn't extra space in the window the content runs right along the edge of the window – making it both visually unappealing and somewhat difficult to read. Is there anyway I might be able to add in some padding or a border around the content to get around this? The website in question is thecollegecook.com
