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.
