That's why I mentioned the PNG case of partial transparency which confuses the issue. Transparency in an image can be treated as a special case of partial transparency, and the view tended towards not making opacity (alpha) = 0.000 a special case. > If it refers to images was this implemented? > why does it only relate to png and not gif images? > perhaps someone could expand? Unless it has appeared in an errata, one cannot tell what official policy is from the public mailing lists, only attempt to judge the consensus (W3C decision processes are closed; the mailing lists are largely a one way channel into W3C). Even if a clarification is added to an errata, past performance of browser developers suggests that it will take up to four years to get implemented - as I already pointed out a problem with links and z-order that doesn't involve transparency has not yet been scheduled for a fix in Mozilla. At the moment, I think that is an ambiguity in the specification (NB W3C specification are deliberately ambiguous in many areas, to allow for different user interface solutions; you need to design to the behaviour guaranteed by the specification not particular implementations).
