Hungry for more DOM? In the last chapter, you got
a crash course in the coolest way to update your web pages:
the Document Object Model. We gured you might be
wanting even more, though, so in this chapter you’ll use what
you’ve just learned to write a nifty DOM-based application.
Along the way, you’ll pick up some new event handlers,
learn how to change a node’s style, and create a user-
friendly, dynamic application. This is the chapter where we
take your DOM skills to a whole new level.
