# PostCSS Input Style
[![NPM version][npm-badge]][npm-url] [![Build Status][travis-badge]][travis-url] [![Dependency Status][daviddm-badge]][daviddm-url]

[PostCSS][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.

_Part of [Rucksack - CSS Superpowers](http://simplaio.github.io/rucksack)_

**Input**

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

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

**Output**

```css
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][selectors])

- `-[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

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

See [PostCSS][PostCSS] docs for examples for your environment.
