Split Layout

This Blueprint is a layout with two sides, sometimes seen in portfolio websites of couples and partners. The idea is to show an initial two-sided view and when clicking on a side, the whole page transitions into the respective direction. The individual page of the selected person is shown.

The Blueprint comes with some example media queries and a second demo where the disappearing side scales down. It will work in modern browsers (from IE9 on).

The HTML
