我在这里有一个正在开发的网站：http://184.173.208.195/~secoast/about/mission它应该有一个“粘性页脚”，但是为了让阴影正确显示在内容的底部，我不得不稍微修改代码。这样做时，页脚现在出现在长页面内容的底部。

这是粘性页脚的代码：

/* Begin Sticky Footer code */
html, body, #wrap       { height: 100%;}
body > #wrap            { height: auto; min-height: 100%; }
#main                   { padding-bottom: 50px; }  /* must be same height as footer 
*/
body.inside #main       { 
    height: 100%;
    margin-top: 5px;
    background: #fff url(../photos/bg_main.png) repeat-y;
    position: relative;
    -webkit-box-shadow: 3px 3px 5px rgba(50, 50, 50, 0.75);
    -moz-box-shadow:    3px 3px 5px rgba(50, 50, 50, 0.75);
    box-shadow:         3px 3px 5px rgba(50, 50, 50, 0.75);
    }

.white-bar-top  { 
    width: 959px; 
    height: 20px; 
    margin-left: 1px;
    background: #fff; 
    margin-top: -10px; 
}

.white-bar-bottom { 
    width: 959px; 
    height: 20px; 
    clear: both;
    background: #fff;
    position: absolute; 
    bottom: 0;  
    left: 1px;
    }   

#footer {
    position: relative;
    width: 100%;
    background-color: #dadfdb;
    margin-top: -50px; /* negative value of footer height */
    height: 50px;
    clear: both; 
}

这是html

我将不胜感激使页脚保持在主要内容下方的任何帮助。

在本地重新创建页面非常困难。您应该考虑创建一个独立的问题示例，以允许其他人进行调试。

但是看看你的编码和你陈述的问题，似乎#footer用 a定位你margin-top: -50px;是导致问题的原因。

#footer {
    position: relative;
    width: 100%;
    background-color: #dadfdb;
    margin-top: -50px; /* negative value of footer height */
    height: 50px;
    clear: both; 
}

您正在定位margin-top: -50px;以使页脚保持不变，但它现在与您的主要内容重叠 -50px，对吗？

所以也许解决方案是给<div>页脚之前的立即数一个 50px 的边距——甚至更多——来补偿？

body.inside #wrap { 
    height: 100%;
    margin-bottom: 50px;
}

我建议您应该使用 Javascript 通过检测窗口高度来执行HARD STOP的操作，如下所示

var ht= window.innerHeight
if(ht< 760){
document.getElementById("footer").style = "width: 100%;background-color: #dadfdb;margin-top: -50px;height: 50px;clear: both;"
}else{
document.getElementById("footer").style = "width: 100%;background-color: #dadfdb;margin-top: -50px;height: 50px;clear: both;position:relative"
}

您可能还想查看 Jquery 的 resize 事件以获取相同的Here

而offCourse 媒体查询是另一种做同样的方式。请看这里
