|
CSS, following the [CSS Color] specification. |

|
a { |
|

|
color: hwb(194 0% 0% / .5); |
|
} |
|
|
|
/* becomes */ |
|
|
|
a { |
|
color: rgb(0, 195, 255); |
|
color: rgba(0, 195, 255, .5); |
|
} |
|
``` |
|
|
|

|
|
|
```bash |
|
npm install postcss @csstools/postcss-hwb-function --save-dev |
|
``` |
|
|
|
Use it as a [PostCSS] plugin: |
|
|
|
```js |
|
const postcss = require('postcss'); |
|
const postcssHWBFunction = require('@csstools/postcss-hwb-function'); |
|
|
|
postcss([ |
|
postcssHWBFunction(/* pluginOptions */) |
|

|
|

[PostCSS HWB Function] 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 determines whether the original functional color notation |
|
is preserved. By default, it is not preserved. |
|
|
|
```js |
|
postcssHWBFunction({ preserve: true }) |
|
``` |
|
|
|
```pcss |
|
a { |
|
color: hwb(194 0% 0%); |
|
color: hwb(194 0% 0% / .5); |
|
} |
|
|
|
/* becomes */ |
|
|
|
a { |
|
color: rgb(0, 195, 255); |
|
color: hwb(194 0% 0%); |
|
color: rgba(0, 195, 255, .5); |
|
color: hwb(194 0% 0% / .5); |
|
} |
