我在这里有一个演示来说明我的问题。

http://www.ttmt.org.uk/forum/

它是页眉、内容和页脚。内容将页脚推到窗口下方，但页脚下方仍有间隙。

为什么页脚下方有空隙？

我需要一个粘性页脚吗？

响应式布局的最佳粘性页脚是什么？

提前感谢您的帮助。

我见过的唯一一个 100% 工作的粘性页脚是这个：http: //jsfiddle.net/DU3uf/

HTML

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>Title of the document</title>
</head>
<body>
    <div id="wrapper">
        <header>

        </header>
        <section>

        </section>
        <div id="push"></div>
    </div>
    <footer>

    </footer>
</body>
</html>

CSS

html, body { width:100%; height:100%; }
#wrapper { width:100%; min-height:100%; height:auto; margin:0 auto -100px; }
#wrapper > header { width:100%; height:100px; background-color:#333; }
#wrapper > section { width:100%; height:400px; background-color:#FFF; }
#push { width:100%; height:100px; clear:both; }
footer { width:100%; height:100px; background-color:#1BA1E2; }

它与引导程序http://getbootstrap.com/使用的相同
