在我的 div 中垂直居中文本而不影响 JQuery

Question

如何在不影响 JQuery 的情况下将我的 div 中的文本垂直居中，我必须将所有 div 设置为相同的高度？我一直在尝试添加前 50 名和左 50 名，但它弄乱了我的 div 的大小。

迫切需要垂直文本！

JS Fiddle

jQuery(document).ready(function($) {

  $(document).ready(function() {
    maxheight = 0;
    $('.main article').each(function() {
      maxheight = $(this).height() > maxheight ? $(this).height() : maxheight;
    })
    $('.main article').height(maxheight);
  });

});

这是我之前用来在 CSS 中实现垂直居中的解决方案。这适用于所有现代浏览器。

<div style="display: table; height: 400px; position: relative; overflow: hidden;">
    <div style="position: absolute; top: 50%;display: table-cell; vertical-align: middle;">
      <div style="position: relative; top: -50%">
        any text<br>
        any height<br>
        any content, for example generated from DB<br>
        everything is vertically centered
      </div>
    </div>
  </div>

对于单行文本，您始终可以使用等于父 () 高度的行高。文本将正确居中（垂直）对齐。
