+
+[PostCSS Focus Within] lets you use the `:focus-within` pseudo-class in CSS,
+following the [Selectors Level 4 specification].
+
+It is the companion to the [focus-within polyfill].
+
+[!['Can I use' table](https://caniuse.bitsofco.de/image/css-focus-within.png)](https://caniuse.com/#feat=css-focus-within)
+
+```css
+.my-form-field:focus-within label {
+  background-color: yellow;
+}
+
+/* becomes */
+
+.my-form-field[focus-within] label {
+  background-color: yellow;
+}
+
+.my-form-field:focus-within label {
+  background-color: yellow;
+}
+```
+
+[PostCSS Focus Within] duplicates rules using the `:focus-within` pseudo-class
+with a `[focus-within]` attribute selector, the same selector used by the
+[focus-within polyfill]. This replacement selector can be changed using the
+`replaceWith` option. Also, the preservation of the original `:focus-within`
+rule can be disabled using the `preserve` option.
+
+## Usage
+
+Add [PostCSS Focus Within] to your project:
+
+```bash
+npm install postcss postcss-focus-within --save-dev
+```
+
+Use [PostCSS Focus Within] to process your CSS:
+
+```js
+const postcssFocusWithin = require('postcss-focus-within');
+
+postcssFocusWithin.process(YOUR_CSS /*, processOptions, pluginOptions */);
+```
+
+Or use it as a [PostCSS] plugin:
+
+```js
+const postcss = require('postcss');
+const postcssFocusWithin = require('postcss-focus-within');
+
+postcss([
+  postcssFocusWithin(/* pluginOptions */)
+]).process(YOUR_CSS /*, processOptions */);
+```
+
+[PostCSS Focus Within] runs in all Node environments, with special
+instructions for:
+
+| [Node](INSTALL.md#node) | [PostCSS CLI](INSTALL.md#postcss-cli) | [Webpack](INSTALL.md#webpack) | [Create React App](INSTALL.md#create-react-app) | [Gulp](INSTALL.md#gulp) | [Grunt](INSTALL.md#grunt) |
+| --- | --- | --- | --- | --- | --- |
+
+## Options
+
+### preserve
+
+The `preserve` option defines whether the original selector should remain. By
+default, the original selector is preserved.
+
+```js
+focusWithin({ preserve: false });
+```
+
+```css
+.my-form-field:focus-within label {
+  background-color: yellow;
+}
+
+/* becomes */
+
+.my-form-field[focus-within] label {
+  background-color: yellow;
+}
+```
+
+### replaceWith
+
+The `replaceWith` option defines the selector to replace `:focus-within`. By
+default, the replacement selector is `[focus-within]`.
+
+```js
+focusWithin({ replaceWith: '.focus-within' });
+```
+
+```css
+.my-form-field:focus-within label {
+  background-color: yellow;
+}
+
+/* becomes */
+
+.my-form-field.focus-within label {
+  background-color: yellow;
+}
+
+.my-form-field:focus-within label {
+  background-color: yellow;
+}
+```
