title: Angular Material button is not rendering
body: <p>I have followed steps to install material design, but when I add button I don't get the MD style.</p>
  
  <pre><code>&lt;button mat-button [matMenuTriggerFor]="menu"&gt;Menu&lt;/button&gt;
      &lt;mat-menu #menu="matMenu"&gt;
        &lt;button mat-menu-item&gt;Item 1&lt;/button&gt;
        &lt;button mat-menu-item&gt;Item 2&lt;/button&gt;
  &lt;/mat-menu&gt;

  <p>I have also added css theme + material design in index.html
  Added MD modules in app.mudule.ts but I get a basic html button style, only the mat-menu-item are in MD style.</p>
  
  <p><strong>Update:</strong> A screen capture of the button:
