1、使用css，參考國外的一個解決方法：

How to use the CSS Sticky Footer on your website

Add the following lines of CSS to your stylesheet. The negative value for the margin in .wrapper is the same number as the height of .footer and .push. The negative margin should always equal to the full height of the footer (including any padding or borders you may add).html

* {web
margin: 0;app
}less
html, body {ide
height: 100%;this
}spa
.wrapper {code
min-height: 100%;htm
height: auto !important;
height: 100%;
margin: 0 auto -4em;
}
.footer, .push {
height: 4em;
}

Follow this HTML structure. No content can be outside of the .wrapper and .footer div tags unless it is absolutely positioned with CSS. There should also be no content inside the .push div as it is a hidden element that "pushes" down the footer so it doesn't overlap anything.

<html>
<head>
<link rel="stylesheet" href="layout.css" ... />
</head>
<body>
<div class="wrapper">
<p>Your website content here.</p>
<div class="push"></div>
</div>
<div class="footer">
<p>Copyright (c) 2008</p>
</div>
</body>
</html>

2、使用js，參考這個：（本人未驗證過，看代碼應該可行）

http://jingyan.baidu.com/article/2fb0ba4054805900f2ec5f9d.html

  //footer吸底效果
    var _ch = $("#content").height();//這個就是你中間內容div的高度
    var _wh = $(window).height();//整個窗口的高度
    //console.log("window's height",_wh,"content's height",_ch,"_wh - _ch:",_wh - _ch);
    if(_wh - _ch > 192){
        $("#content").css("min-height",(_wh-192)+"px");
    }
    //但願這段代碼對你有用！
