Why don't you give a url or at least a bit of the code?
A form element too can be centered using text-align:center.
It doesn't just apply to text.

The trick to center Vertically and Horizontally, is to place the item(s)
you wish to center into a div and then position the div at 50% both
vertically and horizontally and then set its margin-left to negative
width/2 and its margin-top to negative height/2. Of course, you must
know the width and height.

So why put the item in a div first, and not give the
position and negative margins to the item itself?
Also:
- be aware of content becoming inaccessible if the viewport
is smaller than the outer div. (not likely a problem with a
submit button ;-) )
- to use position absolute on the inner div or item, the
outer div needs to be positioned too. This is not always an
option, especially in a flexible design with floats.

Does not work. You forgot that body which contains only absolutely
positioned stuff has 0 height. I may look okey in quirk modes of some
browsers, but that is not making it good.
The ways to vertically center is setting margins of absolutely positioned
to auto, or setting outer containers type to table-cell and using
vertical-align.
There is also other ways to center things: http://www.student.oulu.fi/~laurirai/www/css/middle/
(I still haven't gotten around of making examples centering something on
viewport...)

Well, God knows that there are a lot of things that I don't know, but I
know that it *does* work, also with strict, in Gecko, IE and Opera (with
some calculation problems still in 7.5). You should actually try it
before making such a firm statement! [See example below.]

Well, this will help to get you started (absolute positioning & strict):

Try your code in 40px by 40px window. Of course, it doesn't mather here,
as practically nobody uses that small window (you should see that you
can't see whole box, as you can't scroll to right or up). But if you
would do centering on something bigger, you ran in problems sometimes.
There is no this kind of problem, if you use margins or display:table-
cell to center...
You could get rid of this problem using min-width, but as you only need
to do this kind of centering for IE, it is not really helping much...

I'm sorry, but I just don't understand what you're driving at. It does
not make any sense to make a smaller viewport. If the content is greater
than the viewport, applying overflow:auto for example, will provide
the necessary scrollbars. Does the following example help? Can you make
a modification to demonstrate what you believe to be problematic at times?

No it does not. Try yourself. On the page where you have something
centered in the viewport. Of course it is not possible to see any
downside, if you don't center your thing in viewport, like in example you
included this message.

Maybe you can see if you use this, where I did make the center box a bit
bigger, as you seem to not understand to make your window smaller:
Notice that you can't see whole blue box, even with using scrolbar.

Sure did. To such an extent that it got ridiculous.

I have used this feature to slide a box in and out of view.
It is only a reservation for anyone not able to calculate/envision
dimensions.
Thank you for proving to me that this method is rock solid.
It certainly should be since we're simply centering the top left corner
of the element and then negatively offsetting the element by half of its
width/height in order to achieve centering to the center of the element.
Another advantage to this method, is that we're not limited to only
centering, but being able to place the center of the element to a
specific point in the viewport.

Exacty. This method *requires* moving box outside viewport, as it uses
negative margin. Exeption being when margin is set using percentage.

You still didn't see the problem, did you? The problem is that if the
thing you center is bigger than viewport, content is inaccessible.
Anly way to not get to this trap is to define content size using

Too solid. It is ok as long as you know the minimum width and height of
containing box. In case of viewport, you don't know them, and can't set
them, if browser is IE.

Yes. But when you have bigger element than screen, you get it top and
left edge outside viewport, and you can't access it using any browser. So
this method of centering is not suitable, if you center for example
750px*550px page, as you end up not seeing the heading when you have
400px heigh window. If you use either of other methods, this doesn't
happen. Those other methods don't work on IE to vertically center stuff,
so there is no way to vertically center stuff in IE to viewport, whiout
making assumption that your content will fit the window.

Ok, ok ..... with the *extreme* situation as per your example, this
method is not suitable. Just as for other things, any one method is not
suitable for every given situation. Change a variable and another method
must be considered, or find a workaround. In my opinion, your argument
is not a realistic, real-world example. Why would I wish to center such
a monstrosity? If I wished to center such a thing, then I would simply
use margin:auto;. This has been a response to a real-world requirement
which in my opinion has merit in certain situations. Take it or leave
it, but don't say "it does not work".

You still didn't see the problem, did you? The problem is that if the
thing you center is bigger than viewport, content is inaccessible.
I cannot image anyone so foolish as to not realize that applying a
negative margin, may move the content out of the viewport, depending on
other properties applied. I agree that a *caveat* should be applied to
this method, regarding this, but not that this method does not work. In
fact, I believe that the CSS specs mention such a caveat somewhere. I
can look it up if you wish.
Anly way to not get to this trap is to define content size using
percentage, which most likely causes problems.
Let's not get into hypothetical things again. Thank you for proving to me that this method is rock solid.

them, if browser is IE.
I believe that I was able to give an example with percentages which
worked in Mo, IE and Op. It certainly should be since we're simply centering the top left corner
of the element and then negatively offsetting the element by half of its
width/height in order to achieve centering to the center of the element.
Another advantage to this method, is that we're not limited to only
centering, but being able to place the center of the element to a
specific point in the viewport.
Yes. But when you have bigger element than screen, you get it top and
left edge outside viewport, and you can't access it using any browser. So
this method of centering is not suitable, if you center for example
750px*550px page, as you end up not seeing the heading when you have
400px heigh window. If you use either of other methods, this doesn't
happen. Those other methods don't work on IE to vertically center stuff,
so there is no way to vertically center stuff in IE to viewport, whiout
making assumption that your content will fit the window.
I believe that I have covered this with the "Ok,ok ..." and the *caveat*
above. Are we now in agreement?

Did I actually say "it doesn't work". No I did not. I said "Yes, way that
is most supported. That also breaks easiest, which is a
problem soemtimes."
So, I never claimed it to be that bad, just worse than others, but better
supported.

The problem is that there is no need to use negative margin in
percenteges - if you know margin in percentege, you can just as well
apply it to the thing centered. Yes. But when you have bigger element [...]

I think so. But people try this method very often when centering their
800px wide fixed page, and it fails badly.
