A simple polyfill for the `:focus-ring` spec
npm install @adobe/focus-ring-polyfillA polyfill for the :focus-ring spec.
It is similar to the WICG polyfill, but adds support for dealing with focus programmatically set after an Arrow key or Esc, which is needed for controls like tab lists or dialogs.
Should be used with the postcss-focus-ring plugin to convert this:
``css`
button:focus-ring {
/ focus-ring only stuff /
}
to this:
`css`
button.focus-ring {
/ focus-ring only stuff /
}
This polyfill can then add and remove this .focus-ring to mimic the :focus-ring` spec.
