Is there a way to style HTML5's range control?

Turns out, there is in webkit:

 input[type="range"]{
   -webkit-appearance:none !important;
 }

 input[type="range"]::-webkit-slider-thumb{
   -webkit-appearance:none !important;  
 }

You can then add whatever attributes you need to each those selectors. Background, gradient, etc...

Hope that helps!
