All of the options of purgecss are available to use with the plugins. You will find below the main options available. For the complete list, go to the purgecss documentation website.

Type: string | Object

You can specify content that should be analyzed by Purgecss with an array of filenames or globs. The files can be HTML, Pug, Blade, etc.

extractors

Purgecss can be adapted to suit your needs. If you notice a lot of unused CSS is not being removed, you might want to use a custom extractor. More information about extractors here.

You can whitelist selectors to stop Purgecss from removing them from your CSS. This can be accomplished with the options whitelist and whitelistPatterns.

whitelistPatterns

You can whitelist selectors based on a regular expression with whitelistPatterns.

keyframes

Type: boolean Default value: false

If you are using a CSS animation library such as animate.css, you can remove unused keyframes by setting the keyframes option to true.

fontFace

Type: boolean Default value: false

If there are any unused @font-face rules in your css, you can remove them by setting the fontFace option to true.
