Exploring building websites on a mobile device

These screenshots are the results of an exploration in mobile site builders, as in "building a website on a mobile device". The shots above display how the user would add sections to an existing page (on the right) and edit the navigation bar (on the left).

Two more shots below; both describe how the style editor for a specific section would work. The bottom shot displays a panel allowing the user to edit the background of the selected section. The top shot displays a panel allowing the user to edit the spacing of the selected section.
