Seeing how it works

Obviously this is all designed to be easy peasy, but I've given myself time to figure it out for a reason. Now, just have to work out why the little comic strip is at the bottom of the page instead of at the top. (If I'm not totally stupid, by the time anyone reads this, it will be at the top. If I am, it will either be at the bottom because I gave up trying, or gone because I threw it out in a fit of pique.)
