This sample uses default spinner of fontawesome 4. You may remove the filter in 'loader' class in CSS and see what does it look like originally.

Almost all major browsers support filter but I didn't test it. It might not work on Internet Explorer (as usual). And since filter does some image processing over HTML elements, it might be power consuming or flickering on mobile devices. Use this at your own risk.
