title: JQuery show DIV on another DIV on mouseover
body: <p>I know this may have a simple solution but I'm a Jquery noob. Please, help.
  How can I show a DIV on another DIV on mouseover?</p>
  
  <p>Example, I have this:</p>
  
  <pre><code>&lt;div class="box"&gt; Info about a game &lt;/div&gt;
  </code></pre>
  
  <p>I want to "overlay" another div on the div "box"</p>
  
  <pre><code>&lt;div class="overlay"&gt; Play &lt;/div&gt;
  </code></pre>
  
  <p>How can I do that with JQuery?</p>
  
  <p>Sorry and thanks in advance!</p>
