问题
Now very often content with a certain size centered.
<html>
<head>
<style type="text/css">
#content { margin: auto; width: 960px;}
</style>
</head>
<body>
<div id="content">Blah!</div>
</body>
</html>
Is it safe to not use a wrapper for alignment and size, and apply it directly to a body tag? Like this:
<html>
<head>
<style type="text/css">
body { margin: auto; width: 960px;}
</style>
</head>
<body>
Blah
</body>
</html>

The size is safe, however the margin: auto-centering isn’t completely.
You have to add text-align: center to the body style to center it in IE6, too. (Yeah, I know, it totally makes no sense, but that’s hoe IE6 works)
