Why is this page's body center-aligned?

I am putting together a new site from an existing site and copying over some of the html and css. I don't really understand why the body is center-aligned here: http://www.problemio.com/auth/forg开发者_运维知识库ot_password.php

Any idea what is doing that?

Thanks!

You've got body {text-align: center} in your stylesheet.

The stylesheet being served from Yahoo has body { text-align: center; } in it. You can just put body { text-align: left; } in yours to counter it.
