Hi Davoud, I don't think it centers by default, it simply responds based on the page (or containing DIVs) margins. So if my content is centered by setting left and margin rights to AUTO, then the zoom will center. If the page sits in the upper-left corner of the viewport, then that it how the zoom will respond.
