doc/style.css: make selectors more selective.
doc/style.css: make selectors more selective.

Change #foo to div#foo to avoid selecting headings
with anchor foo, such as <h1 id="foo">.

(A more extensive change would be to use class
selectors for styling. Perhaps this is better, since id:s
should be unique within a document according to
http://www.w3.org/TR/CSS2/selector.html#id-selectors)
