Here is the code that everyone was asking for -- its at the very beginning of development so there isn't much in it yet, which may be helpful...

Here is the css:

@charset "utf-8";
/* CSS Document */

body{
    margin-top: 0px; margin-bottom: 0px; margin-left: 0px; margin-right: 0px;
    padding: 0;
    color: black; font-size: 10pt; font-family: "Trebuchet MS", sans-serif;
    background-color: #E2E2E2;}

html{padding: 0; margin: 0;}

/* ---Section Dividers -----------------------------------------------*/
div.mainContainer{
    height: auto; width: 68em;
    background-color: #FFFFFF;
    margin: 0 auto; padding: 0;}

div.header{padding: 0; margin-bottom: 1em;}

div.leftSidebar{
    float: left;
    width: 22%; height: 40em;
    margin: 0;}

div.mainContent{margin-left: 25%;}

div.footer{
    clear: both;
    padding-bottom: 0em; margin: 0;}

/* Hide from IE5-mac. Only IE-win sees this. \*/
* html div.leftSidebar { margin-right: 5px; }
* html div.mainContent {height: 1%; margin-left: 0;}
/* End hide from IE5/mac */
