🎞️ Prefers reduced transparency

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. It’s around 700 bytes minified, 300 bytes gzipped.

⭐ Usage

Add the dependency from NPM:

npm install prefers-reduced-transparency

Import the package:

import prefersReducedTransparency from "prefers-reduced-transparency";

Then call the function:

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

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

const contrastPreference = prefersReducedTransparency(false);
// Returns "reduce", "no-preference", or "unsupported"
