git clone https://github.com/dracula/highlightjs.git
Download using the GitHub .zip download option and unzip them.
1. Copy dracula.css
to your desired directory.
2. Include the theme in your html. <link rel="stylesheet" href="dracula.css">

<link rel="stylesheet" href="dracula.css">
<script src="http://cdnjs.cloudflare.com/ajax/libs/highlight.js/9.4.0/highlight.min.js"></script>
<script>hljs.initHighlightingOnLoad();</script>
<pre><code class="javascript">
// Scary function
function scare(who) {
console.log(who, 'your blood is mine');
}
</code></pre>
