- # [postcss][postcss]-reduce-initial
- > 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.
