I wanted to implement in java script a horizontal and vertical divider between the 2 windows (or divs) such that - once you drag the divider - it should increase/decrease the width of the left / right or top / bottom  area.

Say for example - in Lotus Notes client - there are 2 dividers 1 vertical and 1 horizontal - vertical divider separates the folder structure and the mails in that folder - and when this divider is dragged it increase / decreases the left and the right area.
Horizontal divider separates the mails and the contents of each mail.

This is a vertical splitter I implemented some time ago. It was made and tested for Internet Explorer only.
<html>
   <style>
      body
      {
         margin: 0;
         overflow: hidden;
      }
 
      div
      {
         height:  100%;
         overflow: auto;
      }
 
      div.left
      {
         background: gold;
         float:      left;
         width:      300px;
         clear:      left;
         cursor:     default;
      }
 
      div.right
      {
         background: salmon;
         float:      left;
         clear:      right;
