A collection of pure CSS spinners, forged by boredom in the dark plains of Sweden. Feel free to contribute with spinners or ideas for spinners!

The spinners are tested in Blink (Chrome) and Gecko (Firefox) and should theoretically work in any Webkit based browser as well. They will definitely not work in IE < 11. I would suggest a fallback to GIF or SVG for older browsers.
