Question

无论页面大小如何，我都试图让我的页脚保持不变。但是当关于div侵占时它会被抛出。我希望它显示在about内容上，但是对于要滚动的内容，它太大而无法显示。这是代码

.footer {
background-color:#FFF;
width: 100%;
border-top: 1px solid #ccc;
padding-top: 1em;
height: 140px; 
display: block;

.about {
font-family: HindMedium;
font-size: 13px;
min-width: 800px;
text-align: left;
width:100%;
min-height: 100%;
margin-bottom: -140px; 
    }

Answer 1

您需要清除浮动。将clear:both;添加到.footer。

＆＃13;

(function() {

  var img = document.getElementById('container').firstChild;
  img.onload = function() {
    if (img.height > img.width) {
      img.height = '100%';
      img.width = 'auto';
    }
  };

}());

＆＃13;

  margin: 0;

Answer 2

从 .about 类中删除这些内容。你应该用保证金练习一些。它不会像你尝试使用它一样工作。

min-height: 100%;  
margin-bottom: -140px;

将 clear：both; 添加到页脚声明中。

同时将您的体型从身高更改为 min-height ，以便您的身体可以比浏览器更大。

Answer 3

您可以在.about和.footer上使用overflow：hidden，这样浮动内容就会保留在这些容器中。您不需要.about上的负边距。如果您试图使页脚停留在页面底部，即使内容很少，您也可以尝试绝对定位页脚。这是下面的一个例子。您需要将所有内容包装在.wrapper或您想要使用的任何名称中。

.wrapper { min-height: 100%; position: relative; }
.article { overflow: hidden; }
.footer { overflow: hidden; position: absolute; bottom: 0; }

内容较少，页脚位于底部： https://jsfiddle.net/suefeng/u4coohpp/1/

内容越多，页脚仍然位于底部： https://jsfiddle.net/suefeng/u4coohpp/3/

如果您希望元素伸出.article和.footer容器，或者只是另一个选项，这里有一个清除浮动的替代解决方案：您可以删除文章和页脚容器上的浮动，但使用display: inline-block;代替vertical-align: top;。您需要* { box-sizing: border-box; }或将填充更改为边距。

https://jsfiddle.net/suefeng/u4coohpp/4/

还将此添加到页脚，以便电子邮件地址不会进入下一列：

.footer a[href*="mailto"] {
    word-break: break-all;
}

这是一个固定页脚的示例： https://jsfiddle.net/suefeng/gv7Lg3e0/1/

.footer {
    position: fixed;
    bottom: 0;
}

Answer 4

如果您只是尝试将元素固定在页面底部并在其下方滚动内容。你应该使用position：fixed。

如果您像这样更新页脚内容：

.footer {
  background-color: #FFF;
  border-top: 1px solid #ccc;
  padding-top: 1em;
  height: 140px;
  display: block;
  overflow: hidden;
  position: fixed;
  left:0;
  right:0;
  bottom:0;
  clear:both;
}

页脚将固定到底部。在页脚之后还需要一个垫片，以确保滚动条足以将所有内容滚动到视图中。

HTML：

<div class='footer-spacer'></div>

CSS：

.footer-spacer {
    height: 160px;
}

从 .about 类中删除这些内容。当边缘移动元素时，负边距将导致奇怪的行为。

min-height: 100%;  
margin-bottom: -140px;

无论内容长度如何，如何将div固定在页面底部？
