Pretty nifty idea, and a great way of introducing someone to web design in a light and straight-forward way.<p>A couple nitpicks: #555 is too light and hurts readability a bit; spacing is exaggerated, 4em padding results in headers too for apart, and the 1.5 line-height ends up breaking apart the paragraph masses. As someone in the field I also wished the font-face section was not there - it's one of the first things to hurt performance on the web and rarely warrants the cost.<p>For the last step, I missed seeing the header since I clicked the bottom-most link (‘one last thing’) instead, and got lost due to back button not working.
