css - 粘性页脚，但只是有时

Question

我有一个带有页眉、内容和页脚的基本站点。我正在寻找的是一种设置页脚样式的方法，以便根据屏幕分辨率，如果内容没有填满页面，它会粘在底部，但如果内容溢出，它会将页脚向下推(必须滚动浏览器以查看页脚)。

<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>
