+
+> Reduce `initial` definitions to the *actual* initial value, where possible.
+
+
+## Install
+
+With [npm](https://npmjs.org/package/postcss-reduce-initial) do:
+
+```
+npm install postcss-reduce-initial --save
+```
+
+
+## Examples
+
+See the [data](data) for more conversions. This data is courtesy
+of Mozilla.
+
+### Convert `initial` values
+
+When the `initial` keyword is longer than the property value, it will
+be converted:
+
+#### Input
+
+```css
+h1 {
+    min-width: initial;
+}
+```
+
+#### Output
+
+```css
+h1 {
+    min-width: 0;
+}
+```
+
+
+### Convert values back to `initial`
+
+When the `initial` value is smaller than the property value, it will
+be converted:
+
+#### Input
+
+```css
+h1 {
+    transform-box: border-box;
+}
+```
+
+#### Output
+
+```css
+h1 {
+    transform-box: initial;
+}
+```
+
+This conversion is only applied when you supply a browsers list that all support
+the `initial` keyword; it's worth noting that Internet Explorer has no support.
+
+
