Web pages are defined by the XHTML code and fleshed out by CSS. But to make them move and breathe, sing, and dance, you need to add a programming language or two. If you thought building Web pages was cool, you're going to love what you can do with a little programming. Programming is what makes pages interact with the user. Interactivity is the "new" in "new media" (if you ask me, anyway). Learn to program, and your pages come alive.
Sometimes people are nervous about programming. It seems difficult and mysterious, and only super-geeks do it. That's a bunch of nonsense. Programming is no more difficult than XHTML and CSS. It's a natural extension, and you're going to like it.
