Fully opaque or fully transparent? I have a container with a rounded border. I have an interesting situation trying to do page transitions (for the client of course). Javascript first does a document.write to add a style element that sets the body's visibility to hidden. Then jquery document.ready sets the opacity to 0 and the visibility to visible. then jquery animates the opacity from 0 to 100%. It is ridiculous but if I don't do it in that order it renders the page before hiding it and fading it in. Anyway the point is that my CSS3 PIE element now has a transparent background and no border.

any news on this one?

Suggest working from the standards css 'opacity' property, rather than parsing 'filter:alpha(opacity=foo)'. Even though 'opacity' is not a css3 property, better to enable the standards. I expect you're already thinking this way.

Will this help with combining opacity and background-image (png) transparency issues in IE - automatically providing the benefits of -pie-png-fix: true; if there is a background image on the element as well? Nice.
