body: <p>I was looking for a solution, but nothing found (only articles about <code>(window:resize)</code>, but it is not I am looking for).</p>
  
  <p>How to detect element size change in <code>Angular 2</code>?</p>
  
  <pre><code>&lt;div #myElement (sizeChanged)="callback()" /&gt;
  </code></pre>
  
  <p>I want to use some <code>CSS</code> animations and detect element's <code>height</code> and <code>width</code> changes.</p>
