title: Specify CSS files per Module in angular2
body: <p>I have angular 2 project which have 2 Modules, one for web and one for admin.</p>
  
  <p>I put the main styles for web in <code>style.css</code> (specified in .angular-cli.json)</p>
  
  <pre><code>@import "../node_modules/bootstrap/dist/css/bootstrap.css";
  </code></pre>
  
  <p>and it work great, but the <code>style.css</code> code appear every where in both web and admin, i want to separate it completely.</p>
  
  <p>is there any way to set specific CSS style files for each Module?</p>
