```bash
npm install --save-dev postcss postcss-opacity-percentage
```

Using [yarn](https://yarnpkg.com/):

```bash
yarn add --dev postcss postcss-opacity-percentage

## Example

### `postcss-preset-env`

If you are using [`postcss-preset-env@>=7.3.0`](https://github.com/csstools/postcss-plugins/blob/main/plugin-packs/postcss-preset-env/CHANGELOG.md#730-january-31-2022), you already have this plugin installed via this package.

## Options

### `preserve`

The `preserve` option determines whether the original percentage value is preserved. By default, it is not preserved.

```js
// Keep the original notation
postcss([
  require('postcss-opacity-percentage')({preserve: true}),
]);
```

```css
/* Input */
.foo {
  opacity: 45%;
}
```

```css
/* Output */
.foo {
  opacity: 0.45;
  opacity: 45%;
}
```
