title: Web component, how to get an element by Id?
body: <p>I want to grab an element by its ID. My template looks like this:</p>
  
  <pre><code>&lt;template&gt;
      &lt;h2&gt;Welcome&lt;/h2&gt;    
      &lt;div id="toGrab"&gt;&lt;/div&gt;
  &lt;/template&gt;
  </code></pre>
  
  <p>I tried using jQuery but the below snippet doesn't work:</p>
  
  <pre><code>$('#toGrab').dosomething();
  </code></pre>
  
  <p>Any idea?</p>
