Razor syntax not highlighting

[dush-a]

I used the Static website or simple usage explained on the readme page.

<script type="text/javascript" src="/path/to/highlight.min.js"></script>
<script type="text/javascript" src="/path/to/highlightjs-cshtml-razor/dist/cshtml-razor.min.js"></script>
<script>
    hljs.highlightAll();
</script>

Then how can I use it on an HTML page?

I tried the following:

<pre><code class="language-cshtml"> cshtml here </code></pre> didn't work, then tried

<pre><code class="language-cshtml-razor"> cshtml here </code></pre> no luck.

Thanks
