This plugin transform this css:

```css
.foo {
  width: clamp(10px, 4em, 80px);
}
```

into this:

```css
.foo {
  width: max(10px, min(4em, 80px));
}
```

Or with enabled options `precalculate`:

```css
.foo {
  width: clamp(10em, 4px, 10px);
}

/* becomes */

.foo {
  width: max(10em, 14px);
}
```

## Instalation

```

## Usage

Use [PostCSS Clamp] as a [PostCSS] plugin:

```js
const postcss = require('postcss');
const postcssClamp = require('postcss-clamp');

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

[PostCSS Clamp] runs in all Node environments, with special instructions for:

| [Node](INSTALL.md#node) | [PostCSS CLI](INSTALL.md#postcss-cli) | [Webpack](INSTALL.md#webpack) | [Create React App](INSTALL.md#create-react-app) | [Gulp](INSTALL.md#gulp) | [Grunt](INSTALL.md#grunt) |

See [PostCSS] docs for examples for your environment.

## Options

### precalculate

The `precalculate` option determines whether values with the same unit
should be precalculated. By default, these are not precalculation.

```js
postcssColorHexAlpha({
  precalculate: true
});
```

The second and third value has the same unit (`px`):

```css
.foo {
  width: clamp(10em, 4px, 10px);
}

/* becomes */

.foo {
  width: max(10em, 14px);
}
```

Here all values have the same unit:

```css
.foo {
  width: clamp(10px, 4px, 10px);
}

/* becomes */

.foo {
  width: 24px;
}
```
