Hi,

I would like to know if a listing of the devices that support
aural CSS exists.  I have tried it with 5 Explorer and Jaws, and
don't work although the page validates in W3C CSS validator.

Thanks in advance,

Ricardo

Asunto: Re: Empty table cells


Just to clearify, my original post was ment more like a question
then like
an answer. The question was

Is the currntly specified behaviour (remove background and
outlines of empty
cells) intended, thus breaking compability with html tables. Or
was it ment
that empty cells should be hidden only when "empty-cells" is set
to "hide"?
