Sometimes you want to provide alternative values also know as _fallback values_. <br>
For example in Internet Explorer 8 there is no `rgba` compatibility for colors which means just passing _e.g. `color: rgba(0, 0, 0, 0.5)`_ would not be applied correctly.
By passing an array of values you can provide fallback values.
## Installation
```sh
yarn add fela-plugin-fallback-value
```
You may alternatively use `npm i --save fela-plugin-fallback-value`.
## 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 fallbackValue from 'fela-plugin-fallback-value'
const renderer = createRenderer({
plugins: [fallbackValue()],
})
```
## Example
#### Input
```javascript
{
color: ['#ccc', 'rgba(0, 0, 0, 0.5)']
}
```
#### Output
```javascript
{
color: '#ccc;rgba(0, 0, 0, 0.5);'
}
```
which is similar to the following CSS code:
```CSS
{
color: #ccc;
color: rgba(0, 0, 0, 0.5);
}
```
