[PostCSS Overflow Shorthand] lets you use the `overflow` shorthand in CSS,
|
||
|
|
following the [CSS Overflow] specification.
|
||
|
|
|
||
|
|
```pcss
|
||
|
|
html {
|
||
|
|
overflow: hidden auto;
|
||
|
|
}
|
||
|
|
|
||
|
|
/* becomes */
|
||
|
|
|
||
|
|
html {
|
||
|
|
overflow-x: hidden;
|
||
|
|
overflow-y: auto;
|
||
|
|
overflow: hidden auto;
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
Add [PostCSS Overflow Shorthand] to your project:
|
||
|
|
|

|
|
```bash

||
|
|
npm install postcss-overflow-shorthand --save-dev
|
||
|
|
```
|
||
|

Use [PostCSS Overflow Shorthand] to process your CSS:

const postcssOverflowShorthand = require('postcss-overflow-shorthand');
|
||
|

postcssOverflowShorthand.process(YOUR_CSS /*, processOptions, pluginOptions */);
|
||
|
|
```
|
||
|
|
|
||
|
|
Or use it as a [PostCSS] plugin:
|
||
|
|
|
||
|
|
```js
|
||
|
|
const postcss = require('postcss');
|
||
|
|
const postcssOverflowShorthand = require('postcss-overflow-shorthand');
|
||
|
|
|
||
|
|
postcss([
|
||
|
|
postcssOverflowShorthand(/* pluginOptions */)
|
||
|
|
]).process(YOUR_CSS /*, processOptions */);
|
||
|
|
```
|
||
|
|
|
||
|
|

|
||
|
|
instructions for:
|

## Options
|
||
|
|
|
||
|
|
### preserve
|
||
|
|
|
||
|
|
The `preserve` option determines whether the original `overflow` declaration is
|
||
|
|
preserved. By default, it is preserved.
|
||
|
|
|
||
|
|
```js
|
||
|
|
postcssOverflowShorthand({ preserve: false })
|
||
|
|
```
|
||
|
|
|
||
|
|
```pcss
|
||
|
|
html {
|
||
|
|
overflow: hidden auto;
|
||
|
|
}
|
||
|
|
|
||
|
|
/* becomes */
|
||
|
|
|
||
|
|
html {
|
||
|
|
overflow-x: hidden;
|
||
|
|
overflow-y: auto;
|
||
|
|
}
|
||
|
