The Docbook DTD for XML provides a rich set of markup for authors of technical documents. However, developing a publication through repeated cycles of (1) editing source code, (2) transforming sources to target format (like HTML or PDF) and (3) reviewing recent changes can become a bit cumbersome, especially when compared with WYSIWYG-style publication tools.
This project provides a set of CSS files for direct inclusion in a DocBook document. They simplify the development cycle by providing previews without the transformation step: Just edit the source and load it into any XML- and CSS-enabled Browser for preview. After changing your text, just refresh the browser display and see the effect.
