# [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: auto;
 | 
						|
}
 | 
						|
```
 | 
						|
 | 
						|
### 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.
 | 
						|
 | 
						|
## API
 | 
						|
 | 
						|
### reduceInitial([options])
 | 
						|
 | 
						|
#### options
 | 
						|
 | 
						|
##### ignore
 | 
						|
 | 
						|
Type: `Array<String>`
 | 
						|
Default: `undefined`
 | 
						|
 | 
						|
It contains the Array of properties that will be ignored while reducing its value to initial.
 | 
						|
Example : `{ ignore : ["min-height"] }`
 | 
						|
 | 
						|
