A Zen sub theme for handbook sites.
The theme focuses on handling marked up content extremely well, helping you to rapidly create handbook sites that are pleasurable to read without having to design everything first.
Apart from proper styling for commonly used HTML elements, there's support for typical 'incorrect'/'correct' examples (as seen in the screenshot.)
[your content] can be anything (
code, and so on).
