Prefers reduced transparency is a package that tells you whether a user prefers less transparency. It's based on the CSS `@media (prefers-reduced-transparency)`, which is part of [Media Queries Level 5](https://drafts.csswg.org/mediaqueries-5/). It's around 700 bytes minified, 300 bytes gzipped.

## ⭐ Usage

Add the dependency from NPM:

```bash

npm install prefers-reduced-transparency

```

Import the package:

```js

import prefersReducedTransparency from "prefers-reduced-transparency";

```

Then call the function:

```js

const contrastPreference = prefersReducedTransparency();

// Returns "reduce" or "no-preference"

```

## 💡 Browser support

This package only works in browsers that natively support `@media (prefers-reduced-transparency)`, so it just returns `"no-preference"` in unsupported browsers. [Current browser support](https://caniuse.com/#feat=prefers-reduced-transparency)

By passing `false` as the argument, you can get `"unsupported"` as the value for unsupported browsers:

```js

const contrastPreference = prefersReducedTransparency(false);

// Returns "reduce", "no-preference", or "unsupported"

```

## 🛠️ Development

Install dependencies:

```bash

yarn

```

Compile Typescript to ES6 before publishing to NPM:

```bash

yarn build

```
