Full screen body container

Hi, I am using the free version of the Bold Photography template, but I have noticed this on my blog using other Catch Themes so I am thinking it's a Wordpress issue, more than a template issue, but I cannot find nor figure out how to get the body container of a page to be full width. It's like... super narrow and there's so much wasted space. This seems to make the mobile view really bad! If the text is more integral between desktop and mobile in the pro version I will buy the pro version so that my users have a better experience, but something has to change so that my folks can read the provided information on their phones. :/ my site is at ownitsports.us and this body container program is happening on any page or portfolio page
