|
[PostCSS Focus Visible] lets you use the `:focus-visible` pseudo-class in
|
|
CSS, following the [Selectors Level 4 specification].
|
|
|
|
It is the companion to the [focus-visible polyfill].
|
|
|
|
```css
|
|
:focus:not(:focus-visible) {
|
|
outline: none;
|
|
}
|
|
|
|
/* becomes */
|
|
|
|
:focus:not(.focus-visible) {
|
|
outline: none;
|
|
}
|
|
|
|
:focus:not(:focus-visible) {
|
|
outline: none;
|
|
}
|
|
```
|
|
|
|
[PostCSS Focus Visible] duplicates rules using the `:focus-visible` pseudo-class
|
|
with a `.focus-visible` class selector, the same selector used by the
|
|
[focus-visible polyfill]. This replacement selector can be changed using the
|
|
`replaceWith` option. Also, the preservation of the original `:focus-visible`
|
|
rule can be disabled using the `preserve` option.
|
|
|
|
## Usage
|
|
|
|
Add [PostCSS Focus Visible] to your project:
|
|
|
|
```bash
|
|
npm install postcss-focus-visible --save-dev
|
|
```
|
|
|
|
Use [PostCSS Focus Visible] to process your CSS:
|
|
|
|
```js
|
|
const postcssFocusVisible = require('postcss-focus-visible');
|
|
|
|
postcssFocusVisible.process(YOUR_CSS /*, processOptions, pluginOptions */);
|
|
```
|
|
|
|
Or use it as a [PostCSS] plugin:
|
|
|
|
```js
|
|
const postcss = require('postcss');
|
|
const postcssFocusVisible = require('postcss-focus-visible');
|
|
|
|
postcss([
|
|
postcssFocusVisible(/* pluginOptions */)
|
|
]).process(YOUR_CSS /*, processOptions */);
|
|
```
|
|
|
|
[PostCSS Focus Visible] 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
|
|
focusVisible({ preserve: false });
|
|
```
|
|
|
|
```css
|
|
:focus:not(:focus-visible) {
|
|
outline: none;
|
|
}
|
|
|
|
/* becomes */
|
|
|
|
:focus:not(.focus-visible) {
|
|
outline: none;
|
|
}
|
|
```
|
|
|
|
### replaceWith
|
|
|
|
The `replaceWith` option defines the selector to replace `:focus-visible`. By
|
|
default, the replacement selector is `.focus-visible`.
|
|
|
|
```js
|
|
focusVisible({ replaceWith: '[focus-visible]' });
|
|
```
|
|
|
|
```css
|
|
:focus:not(:focus-visible) {
|
|
outline: none;
|
|
}
|
|
|
|
/* becomes */
|
|
|
|
:focus:not([focus-visible]) {
|
|
outline: none;
|
|
}
|
|
|
|
:focus:not(:focus-visible) {
|
|
outline: none;
|
|
}
|
|
```
