我已经尝试了许多可能的解决方案，在这里搜索，但没有任何效果，我不知道我做错了什么。我希望你能帮忙吗？ 我的页脚不会被内容向下推，因此当视口不够高时，页脚只会重叠内容。我希望页脚始终位于内容（页面）的底部。不是视口。
以下是我的风格：

<p>It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a
more-or-less normal distribution of letters, as opposed to using ‘Content here, content here’, making it look like readable English. Many desktop publishing packages and web page
editors now use Lorem Ipsum as their default model text, and a search for ‘lorem ipsum’ will uncover many web sites still in their infancy.

有什么建议可能会出错吗？我还注意到，当我使用检查器时，我的html和body都不是100％高度。
答案 0 :(得分：0)
从#content div中删除100％的高度。
在这种情况下（没有父div高度约束），100％表示“视口”的高度，并防止内容推送元素（如页脚）超出该范围。
#content {
width: 984px;
min-height: 100%; /* This line is probably not needed either */
height: 100%; /* Remove this line */
margin: 0 auto;
background:url(../images/contentBG.png) repeat;
margin-top: 54px;
padding: 0 0 80px 80px;
overflow:hidden;
}
如果你发现当最初的内容非常少时你希望页脚显示在视口的底部，然后在有更多内容时被推送，那么你需要一个JavaScript解决方案。
