css2.0 make div background color semi transparent

Hi experts

Using css2.0 is there any way that i can make a div background color semi-transparent, I have to use css2.0 because i am using Visual Web Developer 2008 which only seems to support css2.0.

All modern browsers, including IE9, support RGBA (Red,Green, Blue, Alpha).  
For really old browsers you will want to include a fallback color.

Here's a workaround for older versions of IE.
<!--[if IE]>

   <style type="text/css">

   .color-block {
       background:transparent;
       filter:progid:DXImageTransform.Microsoft.gradient(startColorstr=#99000050,endColorstr=#99000050);
       zoom: 1;
    } 

    </style>

<![endif]-->

The W3C has a demo page at http://www.w3.org/Talks/2003/0521-CSS-WWW2003/opacity2.html that shows using a transparent .png background as a backup for rgba.  This might be useful to you as well.
