1st of all, please try this on a child style first, since I'm not exactly sure it'll work at your board.
I've changed the class and id names a bit for my personal use only.

Put this between your wrapper:

<div class="top_lft"></div><div class="top_rht"></div><div class="top_x"></div>
<div class="header_lft"></div><div class="header_rht"></div><div class="header_x"></div>
<div class="btm_lft"></div><div class="btm_rht"></div><div class="btm_x"></div>

CSS
