Media Query Section Change

I changed the CSS formatting for <section> by making it specific to the .content class after noticing that all sections were set to 10% width. I'm open to other ways of fixing the issue but it was causing the content of my sample blog article to form a single column down the page instead of filling it left to right. 

I haven't added in the link to a pdf yet, but if you there were any ideas from the meeting last week or if you have feedback on the design, I'd be happy to incorporate it.
