The best way to deal with the transparency of PNG background images in IE6

PNG (24-bit) image display is not transparent under IE6 browser.

1. The approach is to useDDPngMin.js

<!--[if IE 6]> 
<script src="js/DDPngMin.js"></script> 
<script>
DD_belatedPNG.fix(‘.ad_img img,#banner_ctr ul‘);
</script> 
<![endif]-->

The first approach is suitable for situations where the color of the background map cannot be represented, and can only be replaced with a picture. And both the background picture and the inserted picture are transparent.

2. Another option is to process PNG (24-bit) images into 8-bit images.

This approach is troublesome, and every picture may have to be dealt with. The picture is reduced, and the quality of the picture is lost.

3. Replace with 16 color values:

Filter:progid:DXImageTransform.Microsoft.gradient (startcolorstr= #22FFFFFF, endcolorstr= #22FFFFFF);

There is no compatibility problem with the third approach, and the use of color code, the client does not need to request pictures again, compared to save resources.
