Well, if we don't use a wrapper div it'll only work in "standard mode",
in which case the 'text-align: center;' on html and 'text-align: left;'
on body won't do anything and are better left out.

A wrapper is used/necessary when mode-independence is important, in
which case the styling should be something like...

body { text-align: center; }
#wrapper { width: 800px; margin-right: auto; margin-left: auto; text-
align: left; }

...for...

<html>
<body>
<div id="wrapper">
..............
</div>
</body>
</html>

...in order to keep older IE/win "quirks mode" versions (of which there
are still a few around) in on the centering-game.
At my end that includes IE6, but that's a personal preference that
sometimes also includes IE7 (etc.).
