html - 页脚不在内容的末尾

Question

我在尝试让页脚实际停留在内容底部时遇到问题。我尝试了 bootstrap sticky footer 示例，但它对我不起作用。感谢任何帮助和代码建议。

这是 CSS。这是一个实时版本，可以查看它在做什么。 https://jsfiddle.net/2f9zsu7d/2/

body {
    background-color: #02060A;
}

#header {
    width: 950px;
    height: 200px;
}

.row.no-pad {
    margin-right:0;
    margin-left:0;
}

.row.no-pad > [class*='col-'] {
    padding-right:0;
    padding-left:0;
}

我认为这就是您想要实现的目标？ https://jsfiddle.net/2f9zsu7d/3/

如果是，则绝对将元素定位在它之前的容器中。这意味着容器将没有与之关联的高度，除非您在其上专门定义了一个高度。我认为您可能想要使用的方法类似于下面的方法。

*, *:before, *:after {
  box-sizing: inherit;
  margin: 0;
  padding: 0;
}
.body {
  background: #efeffe;
}
.header {
  height: 100px;
  background: #bbb;
}
.sidebar {
  width: 250px;
  float: left;
  background: tomato;
  height: 100px;
}
.content {
  margin-left: 275px;
  background: #efefef;
  height: 100px;
}
.footer {
  background: #ddd;
  height: 25px;
}

<div class="body">
  <div class="header">
    <p>This is your header container</p>
  </div>
  <div class="contentWrapper">
    <div class="sidebar">
      <p>This sidebar is floated and has a hard width of 200px.</p>
      </div>
    <div class="content">
      <p>This box is not floated, however is has a margin-left greater than the width of the sidebar.</p>
    </div>
  </div>
  <div class="footer">
    <p>This is your footer</p>
   </div>
</div>
