Each view implements the 'container' div.

Responsibility for implementing the 'container' div has been given to the individual view. This allows for content that occupies the full width of the desktop viewport.

The primary objective here is to allow for a full-width blackboard background on the home page, but it does provide for more view-level customization (specific to the container width) moving forward.
