title: Change size of textarea
body: <p>I currently have a <code>textarea</code> like this:</p>
  
  <pre><code>&lt;textarea matInput rows="5" cols="40" placeholder="text"&gt;&lt;/textarea&gt;
  </code></pre>
  
  <p>However, it is always the same size.</p>
  
  <p>Any idea on how to change the size of the <code>textarea</code>?</p>
