Unfortunately, the HTML and CSS that makes EveryBlock so useful is not included in this release. I'm not sure why the Knight Foundation didn't insist that these components be part of the release, unless the designers were paid out of a separate budget. I understand that releasing these components would have led to clones of the site, but I think, to a certain extent, that is one of the goals of the project.
If you're a programmer (which I think you're not), after watching this video you'll know that the design is not the important thing about EB.
