PostCSS Input Style

PostCSS plugin that adds new pseudo elements to inputs for easy cross-browser styling of their inner elements. Currently the only input supported is Range, more will be added as more vendor-specific pseudo selectors are made available.

Input

 input[type="range"]::track {
  background: #9d9d9d;
  height: 3px;
}

input[type="range"]::thumb {
  background: #4286be;
  width: 16px;
  height: 8px;
}

Output

 input[type="range"]::-webkit-slider-runnable-track {
  -webkit-appearance: none;
  background: #9d9d9d;
  height: 3px;
}

input[type="range"]::-moz-range-track  {
  -moz-appearance: none;
  background: #9d9d9d;
  height: 3px;
}

input[type="range"]::-ms-track  {
  background: #9d9d9d;
  height: 3px;
}

input[type="range"]::-webkit-slider-thumb {
  -webkit-appearance: none;
  background: #4286be;
  width: 16px;
  height: 8px;
}

input[type="range"]::-moz-range-thumb {
  -moz-appearance: none;
  background: #4286be;
  width: 16px;
  height: 8px;
}

input[type="range"]::-ms-thumb {
  background: #4286be;
  width: 16px;
  height: 8px;
}

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

input[type=range]::-moz-focus-outer {
    border: 0;
}

Notes on output:

• Selectors are not grouped because if a browser finds a single selector it doesn't understand in a group, the whole group is ignored (see Selectors Level 3)

• -[vendor]-appearance: none; is added so your custom styles apply. On Chrome and Safari this means you must style both ::track and ::thumb, since the appearance must be set on the root element as well

• The additional ::-moz-focus-outer rule removes the inconsistent dotted focus outline on firefox.

Usage

 postcss([ require('postcss-input-style') ])
