Angular 2 - PrimeNg style not working : <p>I've followed the instruction to install primeng by running <code>npm install primeng --save</code> then importing what I need in the <code>app.module.ts</code> file, for example:</p>

<pre><code>import {CheckboxModule} from 'primeng/primeng';  

...

imports: [
    CheckboxModule,
  ],...
</code></pre>

<p>I then add the style sheets to the index.html file:</p>

<pre><code>&lt;head&gt;
  ...
    &lt;link rel="stylesheet" type="text/css" href="../node_modules/primeng/resources/themes/omega/theme.css" /&gt;
    &lt;link rel="stylesheet" type="text/css" href="../node_modules/primeng/resources/primeng.min.css" /&gt;
    &lt;link rel="stylesheet" type="text/css" href="../node_modules/font-awesome/css/font-awesome.min.css" /&gt;
&lt;/head&gt;
</code></pre>

<p>My IDE can find the file location (by holding ctrl and clicking on the href value) but it is not found by the browser (404 error).</p>

<p>I've copied the checkbox example (<a href="http://www.primefaces.org/primeng/#/checkbox" rel="noreferrer">http://www.primefaces.org/primeng/#/checkbox</a>) and added it to one of my components but the style is the same as a normal checkbox.</p>

<p>Also, no other errors are thrown.</p>

<p>Should the styles be added to another file?  I'm not sure why it's not working.</p>
