[css] Vertically align text within a div

I know it’s totally stupid and you normally really shouldn’t use tables when not creating tables, but:

Table cells can align multiple lines of text vertically centered and even do this by default. So a solution which works quite fine could be something like this:

HTML:

<div class="box">
  <table class="textalignmiddle">
    <tr>
      <td>lorem ipsum ...</td>
    </tr>
  </table>
</div>

CSS (make the table item always fit to the box div):

.box {
  /* For example */
  height: 300px;
}

.textalignmiddle {
  width: 100%;
  height: 100%;
}
