CSS Opacity in IE

This really pissed me off, and took me the best part of an hour to figure out.

With CSS you can set transparency on a container element such as a div, using filter:alpha(opacity=X) where X is a number between 0 and 100 representing percentage of opacity.

What ISN’T stated ANYWHERE is that the container div that will be transparent, for some reason MUST have a bloody height parameter defined!! ARGH!

See Example 3 at this website:

Copy and paste that html code into an empty text file, give it an html file extension and open, should work lovely (remember to change the background:url() bit to point to a file that actually exists).

Remove the height parameter from the div.transbox stylesheet element and it breaks.
