Interesting article Jennifer, I will try some of those things out.
Just to play devil’s advocate for a moment. There is a lot of talk about opacity/transparency in CSS3, but what exactly was wrong with the opacity in CSS2, that works in all browsers, but never much talk about it. I think I have a template thing I did which didn’t include images but I will have to play around with it and find exactly how I did it to be sure.
