title: show/hide a div on hover and hover out
body: <p>I would like to show and hide a div during hover and hover out.</p>
  
  <p>here's what I've done lately.</p>
  
  <p>css</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>$("#menu").hover(function() {
    $('.flyout').removeClass('hidden');
  }, function() {
    $('.flyout').addClass('hidden');
  });</code></pre>
  <pre class="snippet-code-css lang-css prettyprint-override"><code>.flyout {
    position: absolute;
    width: 1000px;
    height: 450px;
    background: red;
    overflow: hidden;
    z-index: 10000;
  }
  
  .hidden {
    visibility: hidden;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.0/jquery.min.js"&gt;&lt;/script&gt;
  &lt;div id="menu" class="margint10 round-border"&gt;
    &lt;a href="#"&gt;&lt;img src="images/menu.jpg" alt="" id="menu_link" /&gt;&lt;/a&gt;
  &lt;/div&gt;
  &lt;div class="flyout hidden"&gt;&amp;nbsp;&lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>My problem is that when I hover on the menu id, the flyout div is blinking.
  why is that?</p>
