?!?
Wait a minute! How did we get here?, you might be thinking, as you find yourself on a sudden new page. Huh! That's weird! (Okay, you are probably not thinking that, but let's pretend for a moment.)
The link didn't take you to a new page: it took you to a new part of the page, previously hidden by some carefully designed <div>s.
Now, you're on a new "page" of the CYOA narrative being written. (Well, it's not much of a narrative at this point, but you get the idea, I hope.)
Go to page 3 for a better explanation, or jump ahead to page 4 to skip to the code.
