have links to the Current and Past pages. The Current page, in turn, has links to reviews about superhero comic books as well as fantasy/horror/sci-fi comics. But what content appears on the Superhero, Fantasy, and Past pages, the ones at the bottom of the organizational hierarchy? To answer this question, simply return to your cards, some of which appear in Table 3-1. According to your content cards, the reviews themselves appear on your bottom-level pages, along with cover images and selected panels from the comics. Table 3-1. Sample content cards and their category labels Content description Card label Current superhero comic reviews Reviews/current/superhero Cover images of currently reviewed superhero comics Reviews/current/superhero Selected panels from currently reviewed superhero comics Reviews/current/superhero Current fantasy comic reviews Reviews/current/fantasy Cover images of currently reviewed fantasy comics Reviews/current/fantasy Selected panels from currently reviewed fantasy comics Reviews/current/fantasy Previous comic book reviews, both superhero and fantasy Reviews/past Cover images of previously reviewed bcomics, both superhero and fantasy Reviews/past Selected panels from previously reviewed comics, both superhero and fantasy Reviews/past   If, however, you plan to write a large number of reviews, you might bog down these pages with too much content, especially the Past page, which combines reviews of both kinds of comics. You may decide to fill your bottom-level pages with links instead, links that go to individual review pages, one for each particular comic book that you review. All it takes is a minor revision to your outline: Comic book reviews Comic book reviews/Current Comic book reviews/Current/Superhero comics Comic book reviews/Current/Superhero comics/Individual review pages Comic book reviews/Current/Fantasy comics Comic book reviews/Current/Fantasy comics/Individual review pages Comic book reviews/Past Comic book reviews/Past/Individual review pages Notice, though, that you're now four levels of organization deep under Current/Superhero and Current/Fantasy. After careful consideration, you decide that you can't justify going beyond the three-level limit in this case, because you don't really need to create separate pages. You can link to reviews of both kinds of comics from the Current page, maybe by dividing the page into Superhero and Fantasy sections. In fact, you like this idea so much that you borrow the same logic for the Past page, and your outline takes the following form: Comic book reviews Comic book reviews/Current (Superhero section, Fantasy section) Comic book reviews/Current (Superhero section, Fantasy section)/ Individual review pages Comic book reviews/Past (Superhero section, Fantasy section) Comic book reviews/Past (Superhero section, Fantasy section)/ Individual review pages Now your outline abides by the three-click rule, and the Current and Past pages are more closely parallel, both of which are excellent organizational attributes for any web site, regardless of content. Apply the same kind of thinking to the remaining content categories, and you can't help but build an effective site structure.
