Redesigns are easier and less expensive

By removing presentational markup from your pages, redesigns of existing sites and content is much less labor intensive (and much less expensive). To change the layout of the site, all you need to do is change the style sheets; you do not need to edit the pages themselves at all.

For example, check out the CSS Zen Garden, or the style switchers on Eric Meyer’s site. To learn more, see Alternative Style by Paul Sowden.
