Pricing slider with HTML/CSS/JS

Well, this one was tough one honestly. The most difficult part was styling of range input. I completed it somehow, but in chrome the range track has no color, i really can't find a good way to style it, whil on Firefox it was definitely easier. JS part with dynamic data was interesting and pretty easy. I can assume, that styling of range inputs isn't best idea. If anyone know any better method to do that, please share, thanks in advance. Also mobile layout was a little tricky with the sorting order of elements, so i've done it in slightly different way, which is a little bit better, i think.
