Help with two DIVs as columns at 100% page height

Question

I've got two DIVs side by side on my page and I want both columns to fill the page from top to bottom.
The left DIV stops about half way down the page.
There are DIVs inside of each column.
My test link is: http://faceworks.webtestingsite.net/pages/facials.html
Here's the CSS I used for the columns,
#leftSideBkgd {
          position:absolute;
          min-height:100%;
          background-color: #f0f0f0;
          width: 25%;
          left: 0px;
          top: 0px;
          z-index: 0;
          background-image: url(../img/bkgd/leftMenu.jpg);
          background-repeat: repeat-y;
          background-position: 100% 0px;
#rightSideBkgd {
          position: absolute;
          background-color: #FFFFFF;
          width: 75%;
          left: 25%;
          top: 0px;
          z-index: 0;
          min-height:100%;
          background-image: url(../img/bkgd/pageBkgd.jpg);
          background-repeat: repeat-x;
          background-position: 0px 0px;
html {
          height:100%;
body {
          height:100%;
          background-image: url(../img/bkgd/pageBkgd.jpg);
          background-repeat: repeat-x;
          margin-left: 0px;
          margin-top: 0px;
          margin-right: 0px;
          margin-bottom: 0px;
          background-color: #FFF;
          font-family: Tahoma, Geneva, sans-serif;
          font-size: 14px;
          font-style: normal;
          line-height: 1.75em;
          font-weight: normal;
          color: #000;
Thanks for your help with this

Answer 1

You cannot safely force the height on those divs, without also getting ugly vertical scrollbars.
Your choices are three -
1.  Use Faux columns (Google it) to make it *look* like the divs are the same height.
2.  Use javascript to actually dynamically determine what height to use for the columns.
3.  Use CSS3 to make the adjacent columns behave as if they were two adjacent cells in a table, resulting in them being the same height.
My preference is #1 - it's easy and VERY effective.  I don't like #2 as a solution, and #3 works beautifully if you are not worried about supporting IE6 or 7.
