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.

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.
