|   Peter, i understand your frustration, so let me try and clarify what is
|   taking place here. What we have is a clash between the ones mental model
| of the page and the actual model of the document.
|   With small document (one that doesn't fill up the browser window) set a
|   border of a few pixels on the body. This should show what you're dealing
|   with. The *body* is as wide as the window, but only as tall as it needs
| to be. 

This is not 100% correct.
You are speaking about 'block' element, but 'inline' element (SPAN) is as 
wide as its contest.
so if you have
<BODY><SPAN>some text</SPAN></BODY>
'some text' will not be 100% of the window width.
BTW: it also illustrates problem with inheritance for inline element's 
width/height. (AFAIK, it's not inherited)
Partial (and wise ) solution for this problem is to use {display: inline-box 
} which apparently *can* have 'width' and 'height'

|This is often times shorter then the height of the browser window
| itself. The minimum height of the document is not the browser height. It's
| because of this that centering a box (div) inside of the containing box
| (body) would not center it in the "box" that is the browser opening.
| Therefore, in reality, CSS doesn't know about the height *or* the width of
| the browser, it just happens that the width of the document IS the width of
| the browser.

you can use
<DIV id="cont" style="width:200px;height:200px">
<DIV id="centerme" 
style="width:100px;height:60px;margin-left:auto;margin-right:auto">how to 
center this block vertically?</DIV>
as a container, and put block to center inside it - see example above.

for 'cont' block, both width and height are known. 
|   Now, i'll withhold any comments on whether I think this is the right
|   approach, I will just say that I've seen *a lot* of folks not expecting
| it to work this way (or wanting it to work differently).

You can count me, too :-)
