Hi John G,
Your question and point is valid. If a person were to center the content of
their page on a fixed width web page that is wider than the browser window,
then you would have to scroll horizontally, and you would alienate many
viewers.
What people are asking for is variable, relative positioning of their fixed
width web page, so that no matter what size the browser window is, the
content of the page is centered in that window. When done properly, there is
no need for horizontal scrolling. Others ask to take it one step further and
want the page width, content and layout to be totally variable so that it
automagically adjusts and fills the browser window regardless of the size.
Publisher has no built-in capability of doing either.
Publisher produces a fixed width web page with absolute positioning that is
left justified. If the typical Publisher web page is 760 pixels wide, left
justified and viewed on a large monitor and a full screen browser window,
all that "white space", or "padding" to the right of the content is
disconcerting to many. They think that having the page centered in the
browser window looks better. It is a matter of taste. The link I provided is
an article by David Bartosik that explains all this much better than I can,
and how to simulate a centered page with Publisher.
