Style input range before and after

Question

I was following this method from CSS-Tricks to style an input range and was trying to use the before and after pseudo classes. Below is the code I have tried:

input[type=range]::-webkit-slider-thumb:before {
    background: #fff;
}

This doesn't seem to do the trick. Can someone help me how to style the slider track. I need a pure CSS solution. Essentially I want it to look like this.

I will also paste the code from CSS-Tricks:

input[type=range] {
  -webkit-appearance: none;
  margin: 18px 0;
  width: 100%;
}
input[type=range]:focus {
  outline: none;
}
input[type=range]::-webkit-slider-runnable-track {
  width: 100%;
  height: 8.4px;
  cursor: pointer;
  animate: 0.2s;
  box-shadow: 1px 1px 1px #000000, 0px 0px 1px #0d0d0d;
  background: #3071a9;
  border-radius: 1.3px;
  border: 0.2px solid #010101;
}
input[type=range]::-webkit-slider-thumb {
  box-shadow: 1px 1px 1px #000000, 0px 0px 1px #0d0d0d;
  border: 1px solid #000000;
  height: 36px;
  width: 16px;
  border-radius: 3px;
  background: #ffffff;
  cursor: pointer;
  -webkit-appearance: none;
  margin-top: -14px;
}
input[type=range]:focus::-webkit-slider-runnable-track {
  background: #367ebd;
}
input[type=range]::-moz-range-track {
  width: 100%;
  height: 8.4px;
  cursor: pointer;
  animate: 0.2s;
  box-shadow: 1px 1px 1px #000000, 0px 0px 1px #0d0d0d;
  background: #3071a9;
  border-radius: 1.3px;
  border: 0.2px solid #010101;
}
input[type=range]::-moz-range-thumb {
  box-shadow: 1px 1px 1px #000000, 0px 0px 1px #0d0d0d;
  border: 1px solid #000000;
  height: 36px;
  width: 16px;
  border-radius: 3px;
  background: #ffffff;
  cursor: pointer;
}
input[type=range]::-ms-track {
  width: 100%;
  height: 8.4px;
  cursor: pointer;
  animate: 0.2s;
  background: transparent;
  border-color: transparent;
  border-width: 16px 0;
  color: transparent;
}
input[type=range]::-ms-fill-lower {
  background: #2a6495;
  border: 0.2px solid #010101;
  border-radius: 2.6px;
  box-shadow: 1px 1px 1px #000000, 0px 0px 1px #0d0d0d;
}
input[type=range]::-ms-fill-upper {
  background: #3071a9;
  border: 0.2px solid #010101;
  border-radius: 2.6px;
  box-shadow: 1px 1px 1px #000000, 0px 0px 1px #0d0d0d;
}
input[type=range]::-ms-thumb {
  box-shadow: 1px 1px 1px #000000, 0px 0px 1px #0d0d0d;
  border: 1px solid #000000;
  height: 36px;
  width: 16px;
  border-radius: 3px;
  background: #ffffff;
  cursor: pointer;
}
input[type=range]:focus::-ms-fill-lower {
  background: #3071a9;
}
input[type=range]:focus::-ms-fill-upper {
  background: #367ebd;
}

Answer 1

It is possible in Firefox and IE -

// Mozilla    
input[type="range"]::-moz-range-progress {
    background: #cc1a1a;
    height: 12px;
    border-radius: 12px;
}
// IE
input[type="range"]::-ms-fill-lower {
    background: #CC1A1A;
    border: 0 solid #000101;
    border-radius: 50px;
    box-shadow: 0 0 0 #000000, 0 0 0 #0d0d0d;
}
input[type="range"]::-ms-fill-upper {
    background: #c0c0c0;
    border: 0 solid #000101;
    border-radius: 50px;
    box-shadow: 0 0 0 #000000, 0 0 0 #0d0d0d;
}

Only one way was for Chrome :before and :after, isn't supported any more (since March 2016). The best I found - is http://rangeslider.js.org/. Also it works fine with Angular JS - https://github.com/danielcrisp/angular-rangeslider

Bit of a delayed reply here:

A pure CSS solution is not possible cross-browser here - IE is the only one that makes this possible via ::-ms-fill-lower and ::-ms-fill-upper

For a full cross-browser solution you'll need to use js. There's an example here that updates CSS gradients with the input's value to do roughly what you're after: http://codepen.io/ryanttb/pen/fHyEJ
