CSSDeadClass

Remove undefined CSS class attributes from your HTML.

Purpose

This Gem will, given a set of HTML files and a set of CSS files, remove any mentions in the class attributes of HTML objects classes that are not defined in the CSS files.

Sample Usage

Given the following files

index.html

<html>
<body>
	<h1 class="happy sad">Heading</h1>
	<p class="red blue">Hello</p>
</body>
</html>

app.css

.red {
	color: red;
}

.happy {
	color: black;
}

Running CSSDeadClass on those two files will change index.html to the following, remove calls to .sad and .blue, as they do not exist:

<html>
<body>
	<h1 class="happy">Heading</h1>
	<p class="red">Hello</p>
</body>
</html>
