html - 垂直对齐标记中的跨度

Question

这是我的标记。解决方案必须针对跨度中的单行或双行动态工作。所以它应该是可以添加到其中每一个并且工作正常的css。从互联网上看，这似乎是不可能的。请证明我错了。

<ul style="text-align:center; list-style-type: none;">
    <li style="width: 200px">
        <a href="http://www.bing.com" style="display: block; height:35px; background: Black;">
            <span>Vertical Align This Text</span>
        </a>
    </li>
</ul>

<ul style="text-align:center; list-style-type: none;">
    <li style="width: 200px">
        <a href="http://www.bing.com" style="display: block; height:35px; background: Black;">
            <span>Vertical Align This Text With Double Line As Well</span>
        </a>
    </li>
</ul>

Answer 1

这对我有用:

<ul style="text-align:center; list-style-type: none;">
    <li style="width: 200px; display: table">
        <a href="http://www.bing.com" style="display: table-cell; height:35px; background: Black; vertical-align: middle; text-align:center">
            <span>Vertical Align This Text</span>
        </a>
    </li>
</ul>

<ul style="text-align:center; list-style-type: none;">
    <li style="width: 200px; display: table">
        <a href="http://www.bing.com" style="display: table-cell; height:35px; background: Black; vertical-align: middle; text-align:center">
            <span>Vertical Align This Text With Double Line As Well</span>
        </a>
    </li>
</ul>

为方便起见的 CSS 代码:

ul {
  list-style-type: none;
}

li {
  width: 200px;
  display: table;
}

a {
  display: table-cell;
  height: 35px;
  background: black;
  vertical-align: middle;
  text-align: center;
}
