> The CSS Zen Garden worked because everyone was using a single markup file. In real life, it doesn't really work

The dream of the CSS Zen Garden never really extended beyond itself. That wasn't the point. The point was to show people "look at all these pages that look nothing like each other: they're all the same HTML." That was the magic.

Keep in mind the context: you still largely needed structural HTML to effect the layout of your page. Almost everybody was building with HTML where the markup was critical to the appearance. Frontpage, Dreamweaver, and every other tool generated almost no CSS—or at least no good CSS.

This isn't my interpretation. From the site itself:

> There is a continuing need to show the power of CSS. The Zen Garden aims to excite, inspire, and encourage participation. ... CSS allows complete and total control over the style of a hypertext document. The only way this can be illustrated in a way that gets people excited is by demonstrating what it can truly be, once the reins are placed in the hands of those able to create beauty from structure.
