- [Vue Single-File Component](https://vue-loader.vuejs.org/spec.html)
|
|||
|

|
## Getting Started
|
|||
|
|
|
|||
|
|
First thing's first, install the module:
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
npm install postcss-syntax postcss-html --save-dev
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
If you want support SCSS/SASS/LESS/SugarSS syntax, you need to install the corresponding module.
|
|||
|
|
|
|||
|
|
- SCSS: [postcss-scss](https://github.com/postcss/postcss-scss)
|
|||
|
|
- SASS: [postcss-sass](https://github.com/aleshaoleg/postcss-sass)
|
|||
|
|
- LESS: [postcss-less](https://github.com/shellscape/postcss-less)
|
|||
|
|
- SugarSS: [sugarss](https://github.com/postcss/sugarss)
|
|||
|
|
|
|||
|
|
## Use Cases
|
|||
|
|
|
|||
|
|
```js
|
|||
|
|
const postcss = require('postcss');
|
|||
|
|
const syntax = require('postcss-html')({
|
|||
|
|
// syntax for parse scss (non-required options)
|
|||
|
|
scss: require('postcss-scss'),
|
|||
|
|
// syntax for parse less (non-required options)
|
|||
|
|
less: require('postcss-less'),
|
|||
|
|
// syntax for parse css blocks (non-required options)
|
|||
|
|
css: require('postcss-safe-parser'),
|
|||
|
|
});
|
|||
|
|
postcss(plugins).process(source, { syntax: syntax }).then(function (result) {
|
|||
|
|
// An alias for the result.css property. Use it with syntaxes that generate non-CSS output.
|
|||
|
|
result.content
|
|||
|
|
});
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
If you want support SCSS/SASS/LESS/SugarSS syntax, you need to install these module:
|
|||
|
|
|
|||
|
|
- SCSS: [postcss-scss](https://github.com/postcss/postcss-scss)
|
|||
|
|
- SASS: [postcss-sass](https://github.com/aleshaoleg/postcss-sass)

## Turning PostCSS off from within your HTML
|
|||
|
|
|
|||
|
|
PostCSS can be temporarily turned off by using special comments in your HTML. For example:
|
|||
|
|
|
|||
|
|
```html
|
|||
|
|
<html>
|
|||
|
|
<body>
|
|||
|
|
<!-- postcss-disable -->
|
|||
|
|
<a style="color: red;"></a>
|
|||
|
|
<!-- postcss-enable -->
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## Style Transformations
|
|||
|
|
|
|||
|
|
The main use case of this plugin is to apply PostCSS transformations to `<style>` tags and `<div style="*">` property in HTML (and HTML-like).
