  <p>My problems are</p>
  
  <ul>
  <li><p>in the <code>&lt;div&gt;</code>, the attribute <code>visible="false"</code> does not work, I have to use style-attribute</p></li>
  <li><p>in the script, <code>.show()</code> never works with either button. However, <code>.hide()</code> (combined with a visible div) works without problems.</p></li>
  </ul>
