Autoprefix all CSS inside an html page - CSS inside style tags and inside style attributes.

Usage

You pass an html string to .process and it returns the processed html.

var htmlString = "<html><head><style>:fullscreen a { transition: transform 1s; }</style></head><body><h1 style='font-feature-settings: \"liga\", \"dlig\";'>Hello</h1></body></html>";

var prefixed = htmlAutoprefixer.process(htmlString);

You can optionally pass cheerio options.

var htmlString = "<HTML></HTML>";

var prefixed = htmlAutoprefixer.process(htmlString, { lowerCaseTags: true } );
// <html></html>
