I think I now understand: Quoting from the "Complete Reference" by 
Thomas Powell.

"Typically, absolute positioning uses the upper-left corner of the 
browser as the origin,
but if posiitoned objects are within positioned regions themselves, 
their origin is the
top-left most coordinate of their container.

The containing box in your html is not absolutely positioned and if you 
do position it
you then have to worry about positioning what follows.

I need
