Difference between “-webkit-text-fill-color” and “color”?

Question

I\'m trying to understand the difference between -webkit-text-fill-color and just simply color? Is there any functional difference? So far as I can

Answer 1

-webkit-text-fill-color can be set to transparent which allows you to do some really interesting things on text, like setting a horizontal gradient. Check out this rainbow text example: http://jsfiddle.net/DoubleYo/qGfzm/
