1 - good questions
2 - in order to allow people to view things in large print without having to
buy a huge screen - it needs to be flowable -- but that may not always be
possible.  

RE using the horizontal scrollbar -- it is almost impossible to scroll back
and forth and keep track of the line you are on.

Try making a window with non flowing text just 15 or 20 char wide and then
read it using h scroll bar.

But we need to find a way to do this that is practical.  Or to put it at
level 3 where it is only done when by those that really want to make a page
accessible as it can be. 

Thoughts?

Subject: question: fixed vs. liquid layout


I have a question: how should we rule about relative/absolute units for 
lenghts?

Do we mean that every layout should be "liquid", or fluid?

Another way of viewing it: is a fixed layout "per se" inaccessible?

Another related question: is a horizontal bar an accessibility (rather 
than usability) issue?

Let a part that pixels are defined as relative units, so that checkpoint 
3.4 in wcag 1 tends to be very ambiguous. But what we need really to do 
to have an accessible layout? Absolutely liquid? ;-)  Ore relatively 
short fixed is good enough (just to fit 640 x 480)? Or fixed layouts are 
not a problem at all, as long as you can use the horizontal scrollbar? 
I've been thinking about it for a long time, and I'd like to hear the wg 
opinions.

Thank you
