Question

尝试修改bootstrap的Sticky footer示例http://getbootstrap.com/2.3.2/examples/sticky-footer-navbar.html以使其具有垂直居中的内容，但仍然无法做到这一点。

完整代码如下。我正在尝试垂直对齐“开始页面内容”和“结束页面内容”注释之间的部分。

感谢任何帮助。

      }

      #wrap {

        /* Negative indent footer by it's height */

      #footer {

Answer 1

在Bootstrap 3中 - 具有垂直和水平内容的粘性页脚。如果您不需要水平中心，请删除类文本中心。

<nav class="navbar navbar-default navbar-fixed-bottom">
  <div class="container">
    <div class="col-sm-12 text-center navbar-text">
        your content....
    </div>
  </div>
</nav>

Answer 2

设置固定高度后，使用padding-top将内容垂直居中。

或者您可以尝试使用您的内容：

vertical-align: middle;
