Nice one aaronsilber, but I actually viewed the css3keyboard demo in latest version of firefox 4.0.1 But was not getting what all are saying. Then thaught that some property’s are not supported here. And then checked in chrome.
Just want to say awesome work.
Also the link http://blog.typekit.com/2011/02/10/type-study-an-all-css-button/
is much good. Have bookmarked it for my next project.
