PCB Singles uses the bottom left 4" by 6" region of the content that is printed by default. If your trace-work lies within the top 5" of the page as printed to a standard 8.5" by 11" piece of paper, the default PCB Singles preview will be blank. Use the x and y location adjustments on the options panel to move your trace-work into view as described in, How do I adjust trace placement?

The options panel includes x and y location options that allow you to tune the placement of your trace work on the PCB. The Preview button on the bottom right corner will appear after modifying these options. Use it to see the adjusted placement.

While PCB Singles produces 4" x 6" boards, users are free to put multiple instances of their design on one 4" x 6" order (panelized boards). Strategically placed lines of small holes can be used to make panelized boards break apart into individual sub boards easily.

The blue border is a margin indicator. Traces can be in the margin but holes should not be.

Since the red-cross hole indicators are drawn in discrete pixel space, they can only be approximations of the true center of your through-holes. Zoom into your trace-work using the vertical slide bar to the left of the preview in order to get a better representation hole centers from the indicators.
