@quid/stylis-plugin-focus-visible v4.11.6

This Stylis plugin is a polyfill for the :focus-visible CSS pseudo-class.

It works in conjuction with what-input to provide a reliable behavior on browsers that don't natively support the :focus-visible pseudo-class.

Example input:

.foo:focus-visible {
  color: red;
}

Example output:

[data-whatinput='keyboard'] .foo:focus,
[data-whatinput='initial'] .foo:focus {
  color: red;
}

Installation

npm install --save @quid/stylis-plugin-focus-visible

# or

yarn add @quid/stylis-plugin-focus-visible

Usage with Emotion

Is it suggested to use this plugin with Emotion's CacheProvider:

import 'what-input';
import { CacheProvider } from '@emotion/core';
import createCache from '@emotion/cache';
import focusVisiblePlugin from '@quid/stylis-plugin-focus-visible';

const emotionCache = createCache({
  stylisPlugins: [focusVisiblePlugin],
});

const App = () => (
  <CacheProvider value={emotionCache}>
    <StyledComponent>
      any children will be able to use `:focus-visible`
    </StyledComponent>
  </CacheProvider>
);

Beware, the cache instance should be shared across the app if multiple CacheProvider components are used. If you define a new cache, Emotion will parse all your styles twice.
