How to make div background color transparent in CSS

Question

I\'m not using CSS3. So I can\'t use opacity or filter attributes. Without using these attributes how can I make the background-color

Answer 1

Opacity gives you translucency or transparency. See an example Fiddle here.

-ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=50)";       /* IE 8 */
filter: alpha(opacity=50);  /* IE 5-7 */
-moz-opacity: 0.5;          /* Netscape */
-khtml-opacity: 0.5;        /* Safari 1.x */
opacity: 0.5;               /* Good browsers */

Note: these are NOT CSS3 properties
