Pure CSS percentage circle

I found this really nice percentage circle and simply loved it. Since I found nothing like this on github and I needed the source code in LESS, I just transformed the SASS code to LESS and put it into that repo for reuse or further development.

Thanks a lot to André Firchow, who developed this circle. For more information go to his blog: http://firchow.net/css3-prozentanzeige-kreis/. A live demo can be found here: http://circle.firchow.net/
