all,      I decided to try to find out what the actual default
line-heights  are in various browsers.  I quickly got
sidetracked by the actual  behavior of browsers in laying out
lines of text on my test page.  Thing is, I'm not 100% I know
what's going on, nor what should be  going on.  So I came here
in hopes of assistance.     My test file is here:   Here's what
I've observed:      * Compared to Firefox (et. al.), both
Internet Explorer and Safari  appear to push font characters
downard by about 7% the height of the  character boxes.  Or
maybe the line box.  Either way, they end up  with descenders
actually protruding from the line boxes.  That can't  be right,
can it?  Firefox, on the other hand, seems to keep the
characters inside the line boxes.     * I put in a 'span' to
surround the test text, and put top and  bottom borders on it.
