Hello Timothy,

I seem to recall someone (Eric?) awhile back saying that EM is not
exactly %, i.e. .8em ~= 80%
I'm sure em and % have differences; I just don't know what they are.
In terms of font size, ems and percentages act exactly the same.
The only difference is in the way they're expressed-- sort of like
the difference between 1000 meters and a kilometer, if you see what I
mean.
So the following two rules are exactly equivalent:
p {font-size: 0.8em;}
p {font-size: 80%;}
...and if I ever said differently, I must have been smoking crack. A
lot of it.
Now, there may be differences in how browsers deal with ems and/or
percentages, especially really old ones like IE3. That I won't try
to deny, as there are some brain cells in the far back of my skull
that seem to hold a dim memory of such things. In any halfway decent
CSS-supporting browser, though, there should be no difference at all.
