Oh my goodness, this is so good. Just when I wrote that child selectors are not possible in IE, Dean Edwards is proving me wrong. He is writing a behavior that will bring most of the wonderful CSS2 stuff (and even some CSS3) to rusty IE5+ on Win. And it’s available under Creative Commons licence.
Read all about it here, and behold the progress here. I’m so excited about this that I’m barely holding myself not to bug Dean about the progress and when he is expecting to finish. From my own experience I know that work is best done when not rushed.
Keep up the good work Dean.
