Hello, Rijk, hello Andy!

I answer in one mail, just not to make any duplicates.

I guess it can be some encoding problems (with mail transfer of attachement 
or message itself)
I just copied code from mail by Håkon Wium Lie <howcome@opera.com> to KWrite,
added some lines and sent to you.

Håkon  uses X-Mailer: VM 6.76 under Emacs 19.34.4, I don't have experience 
with Emacs and can't comment. There is also following note in message header:
X-MIME-Autoconverted: from quoted-printable to 8bit by www19.w3.org id 
may be, something happened when conversion was done.

HTML variants you sent to me work great in Opera5/Lin and Mozilla 0.9.1, so 
problem was in some character. Both of them also work in Konqueror. 
This just makes me wondering: why Mozilla and Opera are so sensetive to some 
character(s)? I can imagine that this can cause some problems to users, 
especially with non-Latin languages.
Ok, I know that Opera5 doesn't support Unicode, but Mozilla IMO should 
overcome such problems, in any case. That's just my opinion, from user's and 
developer's point of view.

Finally, I think that it's good that this fragment of code works in expected 
One more question: horizontal formatting.
                                ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~  ~
for position: fixed, horizontal margins are ignored.
So this code
  margin-left: auto;
  margin-right: auto;
 is somewhat useless.
What can be done here to center it horizontally (use width:300px instead of 
width:100% to compare)?

|   If there's only a single line in the DIV, it will still start at 40%
|   height. Only when the content exactly fills the 20% height, you can
|   call it truly centered vertically. The lack of a 'shrink-wrapping'

|   problems this thread discusses, IMO.

I see your point. Thank for clarification!
Anyway, this example solves one problem (real task!) which I mentioned 
before - to make presentation in 2min. or 5 min. timeframe, after 
brainstorming in small local group, without network/many computers, etc.
We were doing it on _one_ laptop, sitting 5 people around, in Austrian Alps - 
so, probably now you see why I needed it ;-))

Come here, there is a lot of unused land available. :-)
