Aha, that sheds a different light on the problem :)

If it's really a requirement to avoid line wrapping on that caption, we
are out of luck here.

There's more than that to be taken into consideration here.

Creating "tool-tips" through CSS might look attractive at first, but
using this method for a tool-tip may also at times require that one must
specify  ALT="" (for IMG's) and  TITLE="" in the markup of the element
that the CSS tool-tip is set up for.

IE4/5 renders it's own tool-tips (for any element I think) if there's a
TITLE attribute set for it. For IMG's it does the same, or renders the
ALT attribute content as tool-tip if there's no TITLE attribute given.

NS4x renders tool-tips from ALT attributes on IMG's and does not care
about the TITLE at all. (against the HTML specs of course :)

So there's a possibility to end up with two "tool-tips" in some
situations, because stating  ALT="" for an IMG that is informative in
its nature, defeats that IMG's information content in browsing
situations where IMG's can not be rendered.

So even if I think that just this "CSS tool-tip" idea was interesting,
maybe we need to move ahead one step and ask for some CSS possibilities
to style the tool-tip rendering, that is suggested to come out of the
TITLE attribute value, instead?

>Any thoughts?

Not on 'absolute position' sorry to say. I don't use it my self since it
does not "fit" into my personal design habits. There's only a less than
handful browsers that manages CSS1 at a close to correct level today,
and I want things that "works" on a little bit wider spectrum than just
Mozilla. (but it's a damned good rendering agent though already now :)
