In the recesses of my brain somewhere is a memory that it was related to ActiveX, and/or the CSS filter property. You set some special filter value that invoked ActiveX? Maybe I'm remembering incorrectly but if I think about it too deeply I might start screaming and never stop.

Yup it was something like that. I think it was the opacity property. IE6 required a custom property so in order to do opacity you had to set at least two CSS properties, might have actually been more because Safari/Firefox/Opera/IE mostly had opacity as a CSS extension.

I don’t miss those days.
