Question

我有代码，包含标题，容器（内容）和页脚，我无法将容器垂直对齐，我可以这样做：

html, body {
  height: 100%;
}

footer {
  height: 50px;
  background: #eee;
  text-align: center;
  line-height: 50px;
  position: absolute;
  width: 100%;
  bottom: 0;
}

.text {
  padding-bottom: 20px;
}

如何考虑高度页眉和页脚与绝对位置垂直对齐中心容器;？请帮我。我有4列col-md-6。

示例：http://jsbin.com/miboyuqewu/edit?html,css,output

Answer 1

使用FlexBox

.container {
  display: flex;
  align-items: center;
  height: calc(100% - $navHeight - $footerHeight);
}

但我建议您为容器添加父div并定位.body-content

<div class="body-content">
  <div class="container">
    @content
  </div>
</div>

Answer 2

您可以使用CSS3 transform翻译内容的位置。

执行以下操作：

将包装类添加到内容容器中。
将position: relative;添加到正文的CSS。

对于新的包装类，添加以下CSS：

.wrapper {
  position: absolute;
  top: 50%;
  -webkit-transform: translateY(-50%);
  -ms-transform: translateY(-50%);
  transform: translateY(-50%);
}
