Well I am speaking at the Edge of the Web Conference in Perth in November. The title Progressive Enhancement with CSS: Or how I stopped worrying about IE6 and starting loving CSS3.
The aim is to show how you can use CSS2 and CSS3 to improve the experience of visitors using modern browsers, while not blocking access to those people still using older browsers like IE6. I want to convince the audience, that you can build sites that do not have to look the same in all browsers.
I will be looking at what CSS2 and CSS3 you can safely implement now. The main provision it must not break IE6. It does not have to work in IE6, just have a safe fallback position.
The presentation is not aimed at people who read Surfin Safari, CSS3.info or similar sites and then go off an experiment with what they have been shown. That is what I do
I know I will be covering those I covered indepth before like opacity/transparency and @font-face. Are there any other CSS2 or CSS3 properties you would like to see me cover? Otherwise I might go all shock and awe with transitions ;-)
