html - How do I center something with CSS so that it is centered relative to the scroll bar?

Question

I have centered a div on a page for a group project and while the div itself is centered, the websites contents are centered with the scroll bar in mind. What I mean by this is that the web page contents are centered so that the width of the screen is measured without the scroll bars width. So if the monitor was originally 100px wide, it gets read as 100-(scroll bar width) px wide. Unfortunately, this has caused my fixed position div to be a scroll bars width off center from the rest of the site and it looks pretty funky. Any way to fix that? Can't use jquery, can potentially use a little bit of JS.

同样，这个问题似乎相当模糊。
