( #3333=superdoc: print w/ replies, xml ) Need Help??

Earlier today (23 Sept 2004, local to author), Corion and I briefly talked about the idea of a script for composing and testing CSS for use on the site. The idea I have looked at so far has been rather basic. It involved writing a script that acted as a standalone server, capable of serving up a form for a web browser for writing the CSS, saving the submitted form content (CSS) to a file, and serving up both the CSS file and a sample page, to allow examination of the effects of the CSS.

My quandry is thus: what node or nodes would one suggest could be used or adapted for use as test content?

(And in case anyone is interested, or would like to improve on the basic code I have worked on, I have included it below, in <readmore></readmore> tags.)
