title: Ionic2 - How to import css files for a page component
body: <p>I have to import some stylesheets residing inside node_modules (bootstrap.css from node_modules, etc).
  I tried by </p>
  
  <ul>
  <li>adding styleUrls inside @Page, </li>
  <li>putting the styles in the .scss file inside the page component folder,</li>
  <li>and finally putting the styles inside the template file itself by creating new style tag... all with no luck, i.e the required styles are not getting applied on tags with appropriate classes.</li>
  </ul>
  
  <p>How to do this ?</p>
  
  <blockquote>
    <p>PN: I had imported the page scss for my components in app.core.scs.
    Anyways, I think putting bootstrap.min.css inside page scss is not a
    good way</p>
