I am toying with a javascript scrollbar for a DIV, and am trying to
make it as accessible as possible, I have succeeded on the most part,
but there is a slight problem due to the fact that it isn't a real
scrollbar, I believe the best way is to detect whether overflow is
required, then have it display the newscrollbar and hide the old one!
Anybody have any ideas on whether this is possible, was previously
trying to get style.height, but was not getting any value for the
resizeable box as nothing had been declared, it was resized via text.
Cheers for any help you may be able to give.

awesome, that seemed to do the job perfectly, the only problem is that
it doesn't pick up when the user changes the font size in the browser,
is there a way to get a javascript function to run when the user does
this?
Cheers for your help

Just specify fixed font.

<style type='text/css'>
body {font-size:14pt;}

Users can still alter the text size even if font-size is set. For
example in firefox you just hold down ctrl and move the mouses scroll
wheel to increase/decrease the font-size.
So sadly this wont get around my problem in the long term! Any other
ideas please.

No, your problem seeme to be, that you expect html on different browsers
and different browser settings to show exactly the same correct picture.
That is not what html and the www is about, you should expect a
reasonable nice view on the majority of browsers, standard settings and
standard available fonts, and so also a reasonable javascript effext on
view manipulation.
... in the long term ...
I don't know what you mean by that n this case.

It isn't wrath, it is merely complete incomprehension how someone could post
such a nonsense *knowlingly*.
><style type='text/css'> body {font-size:14pt;}
That font size will be different among computers because the `pt' size is
defined by the font resolution which in turn is defined by the display
resolution which is defined by the capabilities of the underlying graphics
hardware and of the GUI. And, as the OP observed, pt-sized fonts can be
scaled everywhere.
px-sized fonts cannot be scaled per menu in Internet Explorer 6. However,
since the actual pixel size depends directly on display resolution (which
can render the px-sized font illegible as well), it is not a unit
recommended for screen fonts.
It is common knowledge that font sizes for the screen should be specified
using the units `em' or `%', with 1em = 100% being relative to the font-size
of the next font-size formatted ancestor element, or to the default user
stylesheet.
></style> [...]
Please trim your quotes as you already have been asked to.
Users can still alter the text size even if font-size is set. For
example in firefox you just hold down ctrl and move the mouses scroll
wheel to increase/decrease the font-size.
Or press Ctrl+[+-].
So sadly this wont get around my problem in the long term! Any other
ideas please.
Since there is no cross-browser event for scaling fonts, it would appear
that you are out of luck.

Oh, dear pointed, when do you start to be all ears to the problem first,
so that your often to the point[ed] remarks would hit the mark?
The absolute measures of the points, pointed, are not important here,
only that they do not change with simple browser size changing
AFTER page completion and offsetHeight detection.
This would help under IE, but less so in other browsers.

Cheers, guys, a friend has just suggested another idea, and that is to
watch offsetHeight, so I would need to set up an eventListener, so
that as offsetHeight changes, it runs a function. Sorry about the
newby questions, but any help would be much appreciated.
