Position a Semi-Transparent Div on Top of Another

Is it possible to position a DIV on top of another?

I’m building something whereby the content of a DIV needs to be grayed-out based on user interaction, but with the content still being semi-visible. Very similar to an AJAX Modal Popup.

I’ve got the semi-transparency working and the DIV displaying/hiding as needed, but the problem is the positioning of it.

[CODE]
#div1 { z-index:1; }
#div2 { z-index:2; }
[/CODE]

The highest number will be the top. You can see how it works here.

@khorinshizucorFeb 03.2011 — Try "position:absolute" for both divs and the z-index values I suggested and see how that works for you.

Success!
