`npm install @csstools/postcss-media-queries-aspect-ratio-number-values --save-dev`

[PostCSS Media Queries Aspect-Ratio Number Values] lets you use non-integer numbers and `calc()` in `aspect-ratio` feature queries following the [Media Queries 4 Specification].

```css
@media (min-aspect-ratio: 1.77) {}

/* becomes */

@media (min-aspect-ratio: 177/100) {}
```

## Usage

Add [PostCSS Media Queries Aspect-Ratio Number Values] to your project:

```bash
npm install postcss @csstools/postcss-media-queries-aspect-ratio-number-values --save-dev
```

Use it as a [PostCSS] plugin:

```js
const postcss = require('postcss');
const postcssMediaQueriesAspectRatioNumberValues = require('@csstools/postcss-media-queries-aspect-ratio-number-values');

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