title: Get an element from an ID by.css() in protractor
body: <p>Using protractor, I would like to get a canvas which is in div. For example like this:</p>
  
  <pre><code>&lt;div id="myId"&gt;
   &lt;canvas&gt;&lt;/canvas&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>Unfortunately, the canvas can not have an id for some reasons. 
  Therefore, I would like to know if it was possible to do something like that with protractor:</p>
  
  <pre><code>let myCanvas = element(by.css('#myId &gt; canvas'));
  </code></pre>
