CSS3 opacity support in Konqueror 3.1+ and Safari

[DU]

According to a recent post, it seems that Konqueror 3.1+ and Safari 1.1 support CSS3 opacity style property under a proprietary name:

"Support for the CSS3 opacity (using -khtml-opacity) property. Make entire blocks and inlines transparent without resorting to transparent PNGs."

Now, I have a demo page which works for MSIE 6 for Windows and Mozilla-based browsers but since I don't have Linux installed (and don't have Mac OSX 10.3) and since I can not test such demo with Konqueror 3.1+ and/or Safari 1.1, I wish someone could test this and tell me if the demo works.

In particular, I don't know for sure how to declare that property and how to access it.

In the code, I declared it as
-khtml-opacity:0.7 (initial opacity is set to 70%)
and accessed it as
objRef.style.KhtmlOpacity = newValue;

I could not find documentation on this matter anywhere. Do you know where I could find such documentation on such issue? I believe both Safari 1.1 and Konqueror 3.1+ support DOM 2 event interface: document.addEventListener should be true. Am I wrong?

Is the demo working in Konqueror 3.1+ and/or in Safari 1.1? If not, do you know the correct way to declare and access the style property?
