Hi Dan Sorensen,
"sfPublicWrapper" is set to the wrapper of all public pages if they are not based on a masterpage (it is not set to the body tag). You can use it for styling purposes.
The CSS rule set applied to this class in Basic theme (the default public theme which comes with a blank Sitefinity installation) is:
margin: 20px auto;
If you set another public theme to your website this rule set will not be applied.
Let us know if you need further help.
