Put this into your <BODY> section

<div id="theBox"><span>This is the content</span></div>
<script type="text/javascript">fitTextInBox('theBox');</script>
<br>
<div id="theBox2"><span>www.dhtmlgoodies.com</span></div>
<script type="text/javascript">fitTextInBox('theBox2');</script>
<br>
<div id="theBox3"><span>Max height of this box is set to 50px</span></div>
<script type="text/javascript">fitTextInBox('theBox3',50);</script>

How to use

You use this script by defining a <DIV> with an ID. This div should contain one <SPAN> tag which holds the text. Example:
<div id="theBox"><span>www.dhtmlgoodies.com</span></div>
<script type="text/javascript">fitTextInBox('theBox');</script>

The fitTextInBox() function will autofit the text into it's parent DIV. The arguments to this function is the ID of your DIV. The second argument is optional. Use it if you need to define a maximum height. The width of the div is set in the CSS:
  #theBox{
    width:500px;
    border:1px solid #CCC;
    color: #317082;
  }
