Composer does a great deal ”too much, in fact, for this chapter to even scratch the surface. Still, in this chapter, you've wrapped your arms around the job and learned how to get into, out of, and around Composer. As mundane as those tasks are, they're the essential foundation to productive Web authoring. You're on your way.
But for all that Composer is, one thing it is not is smart. It can't tell you whether the content you've created is well organized, well presented, or well written. And although it applies HTML tags to your document dutifully, it cannot tell you whether you've selected the most effective tags for presenting the content at hand.
Thus, Composer is a replacement for only time and labor, not for judgment. To author an effective Web document, you must acquire a sense of Web aesthetics. You pick up much of this sense as you work through this book. But you must also study other pages you see online and mentally catalog the design aspects and content approaches that sing to you ”and those that annoy, bore, or baffle you.
