Brenden,
But how will he manage background-image css property for div? I've developed several websites with responsive design and everytime UI developers want to add image as background for content block (besides the image tag) and clients want to manage it when they populate content for pages.
And if the content zone is single for the page, it's possible to use page type field and manage it on the Form tab and use content before property for zone, otherwise it's weird.
