Question

I am using less in order to make a div with a background colour transparent.

Here is my code which does not work for IE8:

background-color: fade(@mycolor, @transparency);

My question is:
what is the best way, since I am using less, to get the same effect on IE8?

Answer 1

I don’t know about LESS, but you can achieve alpha transparency in IE 7+8 by using a MS gradient filter and set the same color as start and end. The alpha channel is the first two hex digits, RGB following:

/* ARGB backgrounds for IE 7+8 (white background with nearly 90% transparancy) */
section {
    filter: progid:DXImageTransform.Microsoft.gradient( startColorstr=#E5FFFFFF, endColorstr=#E5FFFFFF );
    -ms-filter: progid:DXImageTransform.Microsoft.gradient( startColorstr=#E5FFFFFF, endColorstr=#E5FFFFFF );
}
