21899 - Issues with GFX scrollbars and CSS

Status: RESOLVED WONTFIX

(Core :: XUL, defect, P3)

Description

[Hixie (not reading bugmail)]

There are some issues with the CSS support of GFX scrollbars.

 * <scrollbar> doesn't appear to support 'margin'.
 * <scrollbar> doesn't appear to have a clear way of setting its size (e.g.
   using 'height' or 'width'). If it did, then its children could use
   percentage sizes which would make much more sense.
 * <scrollbar> doesn't take 'padding' into account when working out its
   width/height. For example, stick:
      scrollbar { padding: 20px; }
   ...into xul.css and the scrollbars will stick out of the bottom of your
   windows when you restart Mozilla. (THIS IS DEFINITELY A BUG!)
 * thumb doesn't appear to support 'height' or 'width' either.
 * etc.

There does not appear to be a spec anywhere saying what we can expect scrollbars
to support, style-wise. Nor could I find a relevant bug. If any of these issues
are already covered somewhere or are known deficiencies for which there is no
plan to ever provide support, then that's fine... but it should be documented
somewhere! :-)

One problem per bug report please!  The others should be broken into separate
bugs so we can fix, track, close, test, etc. independently.
assigning to evaughan for triage.

evaughan: Assuming that "triage" means "break this bug into little bits", I
would be happy to do it. If that would help you, feel free to reassign the
bug to me. Cheers!

Triage has the usual medical meaning, just think of software defects as wounds.
It would certainly help to break this into separate bug reports, but you don't
need this one assigned to you in order to do it.

Comment #2 talks about "break this bug into little bits", any progress with this?
Close this bug and create 4 new ones?

I'm guessing this is too old to still be useful, and/or invalid/incomplete

The bug assignee didn't login in Bugzilla in the last 7 months.
:enndeakin, could you have a look please?

I don't think we need to support scrollbars outside the context of scrollable areas. Instead if a usecase arises, we should file a bug for that with a testcase.
