Adds style isolation to every rule by attaching `all: initial` to every class.

_If you just have classname collisions, please take a look at [the advanced Renderer configuration](https://fela.js.org/docs/advanced/RendererConfiguration.html) first._

## Installation

```sh
yarn add fela-plugin-isolation
```

You may alternatively use `npm i --save fela-plugin-isolation`.

## Usage

Make sure to read the documentation on [how to use plugins](https://fela.js.org/docs/latest/advanced/plugins#using-plugins).

```javascript
import { createRenderer } from 'fela'
import isolation from 'fela-plugin-isolation'

const renderer = createRenderer({
  plugins: [isolation()],
})
```

### Configuration

##### Parameters

|  Parameter | Value     | Default | Description                              |
| ---------- | --------- | ------- | ---------------------------------------- |
| exclude    | _(Array_) | `[]`    | CSS properties that will not be isolated |

##### Example

```javascript
import { createRenderer } from 'fela'
import isolation from 'fela-plugin-isolation'

const isolationPlugin = isolation({
  exclude: ['boxSizing', 'display'],
})

const renderer = createRenderer({
  plugins: [isolationPlugin],
})
```

## Example

Using the above example code:

#### Input

```javascript
{
  fontSize: 15,
  color: 'red'
}
```

#### Output

```javascript
{
  all: 'initial',
  boxSizing: 'inherit',
  display: 'inherit',
  fontSize: 15,
  color: 'red'
}
```

## Disable isolation

To disable style isolation for single rules, simply add the `isolation: false` property to that rule.

##### Example

```javascript
const rule = (props) => ({
  isolation: false,
  fontSize: 15,
  color: 'red',
})
```
