+# [postcss][postcss]-ordered-values
+
+> Ensure values are ordered consistently in your CSS.
+
+
+## Install
+
+With [npm](https://npmjs.org/package/postcss-ordered-values) do:
+
+```
+npm install postcss-ordered-values --save
+```
+
+
+## Example
+
+Some CSS properties accept their values in an arbitrary order; for this reason,
+it is entirely possible that different developers will write their values in
+different orders. This module normalizes the order, making it easier for other
+modules to understand which declarations are duplicates.
+
+### Input
+
+```css
+h1 {
+    border: solid 1px red;
+    border: red solid .5em;
+    border: rgba(0, 30, 105, 0.8) solid 1px;
+    border: 1px solid red;
+}
+```
+
+### Output
+
+```css
+h1 {
+    border: 1px solid red;
+    border: .5em solid red;
+    border: 1px solid rgba(0, 30, 105, 0.8);
+    border: 1px solid red;
+}
+```
+
+
+## Support List
+
+For more examples, see the [tests](src/__tests__/index.js).
+
+* `animation`, `-webkit-animation`
+* `border(border-left|right|top|bottom)`
+* `box-shadow`
+* `outline`
+* `flex-flow`
+* `transition`, `-webkit-transition`
+
+
+## Usage
+
+See the [PostCSS documentation](https://github.com/postcss/postcss#usage) for
+examples for your environment.
