I'm sorry, but I don't understand how em-based widths have anything to
do with preventing horizontal scrollbars. It seems as if you and Georg
want the following conditions to be met:
1. Text scales with the user's preferences.
2. All content fits horizontally on the page.
#1 is accomplished by setting font sizes in a relative unit.
#2 is accomplished by setting the width of a container in a percentage.
So what do either of your goals have to do with em-based design? The
point of using ems is:
3. To keep proportions of page elements the same so that line lengths
remain the same (to keep them readable).
But #3 is in direct conflict with #2. There's nothing wrong with this
-- you just have different goals than Al. There are very probably
designs where #2 is a more useful goal than #3, and very probably
designs were #3 is a more useful goal than #2.
I won't get into what my goals are in general -- that's irrelevant --
but I will say that I agree completely with Al's point: you completely
defeat the purpose of using ems for widths if #2 is one of your goals.
Again, there's nothing wrong with goal #2, but it has nothing to do with
ems.
