title: possibilities with local variable
body: <p>Im wondering what are the possibilities with a local variable.
  I know following :</p>
  
  <ol>
  <li><p>You can get a value</p>
  
  <pre><code>&lt;select #selectField (change)="funtionBla(selectField.value)" 
     &lt;option value="1"&gt;1&lt;/option&gt;
     &lt;option value="2"&gt;2&lt;/option&gt;
  &lt;/select&gt;
  </code></pre></li>
  <li><p>You can call methodes of directives</p>
  
  <p></p>
  
  <pre><code> &lt;button type="button" (click)="directiveBla.myFunction()"&gt; test &lt;/button&gt;
  </code></pre></li>
  </ol>
  
  <p>or HTML based</p>
  
  <pre><code>&lt;video #movieplayer ...&gt;
    &lt;button (click)="movieplayer.play()"&gt;
  &lt;/video&gt;
  </code></pre>
  
  <p>But is there a way to change style things of a element VIA Local Variable or is it possible to append an element to a referenced one?</p>
