I am wondering how/where to change the post containing box. I would like to customize the margins and adjust it on the page.
Here is a link to a post site: http://www.travelingapprentice.com/?p=361
I would like it to read more like this: http://www.nytimes.com/interactive/2015/10/27/world/greenland-is-melting-away.html?smid=fb-nytimes&smtyp=cur&_r=1
I have the custom CSS plugin, do I need to add something there to achieve this look?
