Readme
Remove any classes or IDs not found in CSS from HTML - modifies HTML, not CSS.
This only considers CSS contained in the HTML document inside <style> tags to be in use right now. Currently limited to modifying class and id attributes, so won't do anything with [data] or other attributes less commonly used in CSS.
npm install declassify
var declassify = require('declassify');
var result = declassify.process(html);
Input:
<html>
<head>
<style>
.used-class { color: red; }
#used-id { color: blue; }
</style>
</head>
<body class="unused" style="color: black;">
<div class="used-class unused-class"></div>
<div id="used-id"></div>
</body>
</html>
Output:
<html>
<head>
<style>
.used-class { color: red; }
#used-id { color: blue; }
</style>
</head>
<body style="color: black;"> // has removed class="unused"
<div class="used-class"></div> // has removed unused-class
<div id="used-id"></div>
</body>
