Videos overlapping the "Add this" window in IE!_问答_开发者

I have a HTML simple page with a ADD THIS button (the share button actually) and some videos on it. My problem is that when I click on the SHARE button and a small window (a div) pop ups on the center of the browser screen which is keeps it position constant there.

When I scroll the window, this ADD THIS window gets overlapped by the videos on the page. This works good in Firefox but not in IE and Chrome.

Here is my code:

        {
            overflow-y: auto !important;
        }        
    </style>
</head>
<body>

</html>

Any help/comments appreciated.

Well this code required

<param name="wmode" value="transparent">

to be added to the object tag and also the <embed> tag required an attribute as wmode="transparent".

i.e. <embed wmode="transparent" ... />

This worked for me.

Try adding <param name="wmode" value="transparent">

This is a well-known bug in IE, but I'm not sure why it doesn't work in Chrome, so I'm hoping this will solve it for both browsers. Also, have you checked the Z-index just to be sure? (This doesn't matter for IE, but it might for Chrome)
