Less get a cross OS compiler (maybe from a long time, idk) and it’s a good news :)
-prefix-free let you use only unprefixed CSS properties everywhere. It works behin the scene, adding the current browser’s prefix to any CSS code, only when it’s needed.
my advice : It would be a great tool but it’s only compatible with IE9+, Opera 10+, Firefox 3.5+, Safari 4+ and Chrome. The lack of backward compatibility is really pain in the ass and you may consider using other tools like less or saas.
BonBon Buttons - My goal was to create good lookingCSS3 buttons with minimal markup. They use only one PNG for the background noise, everything else is rendered by the browser.. well, so far only Safari, Chrome and Firefox. I’m quite happy how they turned out, but of course, the lack in cross-browser support makes them just another demo.. for now. ;-)
