+# [postcss][postcss]-reduce-idents [![Build Status](https://travis-ci.org/ben-eb/postcss-reduce-idents.svg?branch=master)][ci] [![NPM version](https://badge.fury.io/js/postcss-reduce-idents.svg)][npm] [![Dependency Status](https://gemnasium.com/ben-eb/postcss-reduce-idents.svg)][deps]
+
+> Reduce [custom identifiers][idents] with PostCSS.
+
+
+## Install
+
+With [npm](https://npmjs.org/package/postcss-reduce-idents) do:
+
+```
+npm install postcss-reduce-idents --save
+```
+
+
+## Example
+
+### Input
+
+This module will rename custom identifiers in your CSS files; it does so by
+converting each name to a index, which is then encoded into a legal identifier.
+A legal custom identifier in CSS is case sensitive and must start with a
+letter, but can contain digits, hyphens and underscores. There are over 3,000
+possible two character identifiers, and 51 possible single character identifiers
+that will be generated.
+
+```css
+@keyframes whiteToBlack {
+    0% {
+        color: #fff
+    }
+    to {
+        color: #000
+    }
+}
+
+.one {
+    animation-name: whiteToBlack
+}
+```
+
+### Output
+
+```css
+@keyframes a {
+    0% {
+        color: #fff
+    }
+    to {
+        color: #000
+    }
+}
+
+.one {
+    animation-name: a
+}
+```
+
+Note that this module does not handle identifiers that are not linked together.
+The following example will not be transformed in any way:
+
+```css
+@keyframes fadeOut {
+    0% { opacity: 1 }
+    to { opacity: 0 }
+}
+
+.fadeIn {
+    animation-name: fadeIn;
+}
+```
+
+It works for `@keyframes`, `@counter-style`, custom `counter` values and grid area definitions. See the
+[documentation][idents] for more information, or the [tests](test.js) for more
+examples.
+
+
+## Usage
+
+See the [PostCSS documentation](https://github.com/postcss/postcss#usage) for
+examples for your environment.
+
+
+## API
+
+### reduceIdents([options])
+
+#### options
+
+##### counter
+
+Type: `boolean`  
+Default: `true`
+
+Pass `false` to disable reducing `content`, `counter-reset` and `counter-increment` declarations.
+
+##### keyframes
+
+Type: `boolean`  
+Default: `true`
+
+Pass `false` to disable reducing `keyframes` rules and `animation` declarations.
+
+##### counterStyle
+
+Type: `boolean`  
+Default: `true`
+
+Pass `false` to disable reducing `counter-style` rules and `list-style` and `system` declarations.
+
+##### gridTemplate
+
+Type: `boolean`  
+Default: `true`
+
+Pass `false` to disable reducing `grid-template`, `grid-area` and `grid-template-areas` declarations.
+
+##### encoder
+
+Type: `function`  
+Default: [`lib/encode.js`](https://github.com/ben-eb/postcss-reduce-idents/blob/master/src/lib/encode.js)
+
+Pass a custom function to encode the identifier with (e.g.: as a way of prefixing them automatically).
+
+It receives two parameters:
+  - A `String` with the node value.
+  - A `Number` identifying the index of the occurrence.
