vertical-align不能像大多数初学者期望的那样工作。

Here是一个解释这种情况的教程。听起来你想要方法1。

Answer 3

This tutorial涵盖了一种过去对我有用的方法。

Answer 4

人们可能讨厌我这样做，但是把它放在TD内，垂直对齐仍然可行，而不会对自己造成任何伤害。

我在这里提供了一个工作示例：http://jsbin.com/ezolu3/edit

标记如下：

<table id="vCent">
  <tbody>
    <tr>
      <td valign="center">

        <div id="foo">
          <p>Using tables incorrectly is wrong, without question. But sometimes there are other things that are more wrong - "wrongerer," if you will. Causing yourself unnecessary frustration trying to get an element to center itself vertically, for example, is one of those <em>wrongerer</em> things. Don't bother, just go with what works.</p>
        </div>

      </td>
    </tr>
  </tbody>
</table>

        }
        #wrap
        {
            height: 0px;
            width: 0px;

            position:absolute;
            top:50%;
            left:50%;
        }
        </style>
    </head>
    <body>
        <div id="wrap">
            <div id="content">
                Hello
