Sticky Footer, but only sometimes

问题

I've got a basic site with header, content, footer. What I'm looking for is a way to style the footer so that, depending on screen resolution, if the content doesn't fill the page it sticks to the bottom, but if content overflows it pushes the footer down (have to scroll the browser to see the footer).

<div id="wrapper">
<div id="headwrapper">
<div id="header"></div>
    <div id="menu">
       <ul>
          <li class="active"><a href="#" title="Link1">Link1</a></li>
          <li><a href="#" title="Link2">Link2</a></li>
          <li><a href="#" title="Link3">Link3</a></li>
          <li><a href="#" title="Link4">Link4</a></li>
          <li><a href="#" title="Link5">Link5</a></li>
       </ul>        
    </div>
    <div id="content-container">
          <div id="content">
              <h2>
                  Page heading
              </h2>
              <p>
