postcss-deadclass

Given an array of HTML file names, this class will remove class properties for CSS classes that do not exist in the CSS being processed.

It's pretty much the opposite of postcss-uncss.

Installation

npm install --save-dev postcss-deadclass

Usage

This plugin takes two options:

htmlFiles

An array of HTML file paths, such as one you might generate using node-glob.

classesToKeep

An array of CSS class names to preserve, even if they aren't found in the document. They can be in the form of either classname or .classname.

Example

Usage:

postcss([
	require('postcss-deadclass')({
		htmlFiles: glob('**/*.html'),
		classesToKeep: [
			'apple',
			'.banana',
			'orange'
		]
	})
])

See PostCSS docs for examples for your environment.
