PostCSS HTML Syntax

PostCSS syntax for parsing HTML (and HTML-like)

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
SASS: postcss-sass
LESS: postcss-less
SugarSS: sugarss

Use Cases

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
SASS: postcss-sass
LESS: postcss-less
SugarSS: sugarss

Advanced Use Cases

See: postcss-syntax

Turning PostCSS off from within your HTML

PostCSS can be temporarily turned off by using special comments in your HTML. For example:

<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).
