When you create a word-processing document, you can exercise precise typographical control over some or all of a printed page. Defining the structure of a Web page is a much less predictable process. Get over the urge to control every little formatting feature of your Web pages. The surest way to create a Web page that looks good to all your readers is to trust that your readers' browser will render your page the best it can, if not exactly the way you'd like. Not everyone browses graphically.
Graphics are a great way to spice up a Web page.
But there are at least a million people in the world who, whether of necessity or by choice, don't browse graphically. That's a lot of readers. Build pages that convey their message and navigate easily, even without graphics. When you're new to the WWW, pages that automatically load other pages seem almost magical. But most of the cool stuff you're encountering for the first time has actually been around for quite a while.
