From the look of the screenshot it looks like the poster just applied the standard twitter bootstrap css style sheet to the page.

If you wanna see what it looks like for yourself (and are using chrome) you can use this chrome plugin I wrote: http://scommab.github.com/chrome-twitter-bootstrapper/

Just the link color was borrowed from Twitter Bootstrap. Rest is pretty much white background, max-width, padding between <center> elements on the page, bigger line-height :)

If you send me the CSS (by comment or email from my profile), I know a few people that work at Goddard, and might have a better shot at getting them to add it :)
