I set the display property to table and table cell using CSS.

Ah, clever. I'd missed that. How widespread is support for this usage amongh common UAs?

One quick comment, which is that 'vertical-align' property does not apply to <div/> or other block elements. One has to use either:

(1)

<div>
  <table>
    <tr>
      <td style="vertical-align: bottom">
        <div/>
      </td>
    </tr>
  </table>
</div>

or

(2) use the new CSS3 Box Alignment Module's align-content property [1]:

<div style="align-content: end"/>

[1] http://dev.w3.org/csswg/css-align/#align-content


Note that display-align's {before, center, after} values, correspond to align-content's {start, center, end} values. In particular, start and end are used now in CSS to refer to prior and later edges in a manner independent from the flow axis (block or inline).

I would suggest adopting approach (1) since few UAs support (2) at this time.

Let me know if you see any bugs/gotchas

Thanks
