How do I highlight (make a box appear) under text that has a background color of its own?

I have a way of highlighting text. I position a red box with z-index of -2 where the text should be. This usually works, but not when there is a span element around the text, with an attribute such as: style="background-color:#ffffff". It seem in this case that the red box is covered up. Here is the actual HTML that does not work:

  <article id="ArticleToHighlightRFS">

Neighboring element border problem

Hi there,

I have a problem with displaying borders:

Here is my page:

http://www.deutschschule.net/wb/testing.asp

When you hover the mouse over the boxes on the right, the whole border all around should turn red, but it doesn't.

I tried it with "z-index" and "position", but no change. Is there a pure CSS solution?

By the way, I don't care about IE. It should work on firefox and possibly on other browsers (exept IE).

Thanks ...
