* it's bad to specify only foreground color:
http://www.w3.org/QA/Tips/color
* some people prefer dark background
* `color: #111' is mostly the same as `color: black',
which is the default of almost all popular browsers.
so it's preferable to delete `color: #111', rather than adding
`background-color: white'.
designed loosely based on:
http://mercurial.selenic.com/css/styles.css
with some modifications by intention:
* visited links are colored differently
* no fixed size
* works without typeface.js
we keep most styles, which is from docutils, untouched.
tested with:
* MSIE 6.0 on Windows
* Firefox 3.5 on Linux
