I will try again

Sorry if this ends up being a double post. I just submitted this to the forum a little bit ago, but it never showed up, so here it is again.

This may be a little off topic, but I'm wondering...

On the menu at the top of the page where it says Home, Features, Demo, etc. the features have a drop-down menu. That's not the problem, the problem is making the drop-down tranparent as it is there. I played around with the opacity settings in CSS, but that makes everything contained in the tranparent element also transparent. The text, background color or image and anything else it also transparent.

I see in the menu above that you do not have that problem. Was a semi-transparent .png used as a repeating background image or something like that? If opacity was used, how was it done without making everything else in the element transparent as well?

Thanks.
