Tribute Page feedback request: Guinea Pig Page

Codepen: http://codepen.io/nonTrivialLeaf/pen/MpYbzY

So…

Specific Question: I’m not sure how to get my image and the parent div to play nicely together. I want the parent div to contain the image and text with a white background to match the example, and it does this, but when I view the full screen page the white background extends to the edge of the page and it looks terrible. What is a better way to do this?

Second specific question: I overrode the style of the div containing the img to have a white background. I think the nature of the challange is to not have custom css, to just use bootstrap. What is the right way to define colors using bootstrap?

Beyond that… I am not sure I have any idea what I’m doing. General tips from anyone are greatly appreciated.

Thank you for your time,
