An improvement of DHTML Modal window v1.01?

[jimhap]

1) Script Title: DHTML Modal window v1.01

2) Script URL (on DD):
http://www.dynamicdrive.com/dynamici...dhtmlmodal.htm

3) Describe problem(an improvement):

Maybe this can be more compatabile with Mozilla/Firebird?

Original CSS code(modal.css):

.drag-handle{ /*Overwrite default drag handle bar background color with below*/
background-color: #03277C;
}

#interVeil{ /*CSS for veil that covers entire page while modal window is visible*/
position: absolute;
background: black url(blackdot.gif);
width: 10px;
left: 0;
top: 0;
z-index: 5;
visibility: hidden;
filter:progid:DXImageTransform.Microsoft.alpha(opacity=80);
opacity: 0.8;
}

Possible improved code:

.drag-handle{ /*Overwrite default drag handle bar background color with below*/
background-color: #03277C;
}

#interVeil{ /*CSS for veil that covers entire page while modal window is visible*/
position: absolute;
background: black url(blackdot.gif);
width: 10px;
left: 0;
top: 0;
z-index: 5;
visibility: hidden;
filter:progid:DXImageTransform.Microsoft.alpha(opacity=80);
opacity: 0.8;
-moz-opacity: 0.80;
}

I found that on Google...
Well, even I am a newbie. Is this needed?

"-moz-opacity" is a proprietary CSS syntax only supported in Mozilla browsers. I decided to leave it out and just go with "opacity", which works in Firefox 2.x anyhow.
