# PostCSS Fit Tolerance Property [<img src="https://postcss.github.io/postcss/logo.svg" alt="PostCSS Logo" width="90" height="90" align="right">][PostCSS]

`npm install @csstools/postcss-fit-tolerance-property --save-dev`

[PostCSS Fit Tolerance Property] lets you use the `fit-tolerance` property following the [CSS Grid Specification].  
This initially shipped in some browser versions as `flow-tolerance`.

```css
.foo {
	fit-tolerance: 2em;
}

/* becomes */

.foo {
	flow-tolerance: 2em;
	fit-tolerance: 2em;
}
```

## Usage

Add [PostCSS Fit Tolerance Property] to your project:

```bash
npm install postcss @csstools/postcss-fit-tolerance-property --save-dev
```

Use it as a [PostCSS] plugin:

```js
const postcss = require('postcss');
const postcssFitToleranceProperty = require('@csstools/postcss-fit-tolerance-property');

postcss([
	postcssFitToleranceProperty(/* pluginOptions */)
]).process(YOUR_CSS /*, processOptions */);
```



## Options

### preserve

The `preserve` option determines whether the original notation
is preserved. By default, it is preserved.

```js
postcssFitToleranceProperty({ preserve: false })
```

```css
.foo {
	fit-tolerance: 2em;
}

/* becomes */

.foo {
	flow-tolerance: 2em;
}
```
