Q. How do I do transparency in Microsoft Internet Explorer?

A.
You'll find lots of pages that say you need to specify
the transparency two ways in your CSS:

    filter:alpha(opacity=85); /* for IE */
    opacity: .85; /* Regular CSS */

But I have found from experimentation that IE also requires
a width or height in the CSS.  For example:

    filter:alpha(opacity=85); /* for IE */
    opacity: .85; /* Regular CSS */
    width: 100px;

It makes no sense but that's the way.
Even in IE7.
