Recently on the stylesheets list, Todd Fahrner had this to say:

>What's the difference? Vendors propose all kinds of things. If they are

   The difference I was getting at was this:  vendors may be implementing
properties which have been written into the draft spec. (I think of these
as all being "proposed"), or they might be implementing properties they've
trotted in front of the Working Group but which nobody else has yet
supported.  The first way (mostly) works with the standards system, the
second is an attempt to override the system.

On a related note, Susan Pinochet had this to say:

>I have (incorrectly) used VALIGN in a style sheet to align the contents of
>a TD at the TOP or BOTTOM of the cell. This worked in Netscape
>(Communicator 4.03 for Mac) but not in Internet Explorer (3.01 for Mac).

   I've recently heard that one may also use 'align: left' in the place of
'float: left' in at least one, and possibly both, of the Big Two's
browsers.  What's up with that?
   As a general summary, we've heard of a few proprietary properties:
'layer-background-color', the 'hover' pseudo-class, 'valign' and 'align',
and so on.  If there are more, please let me know (in private e-mail, if
you feel you must).
   Now, how about values which don't appear in the specification?  Anyone
seen any of those?
