如何让绿色div与IE中的DOCX或PDF IFrame重叠？使用z-indexes不起作用。
<html>
<head>
<style>
html, body {
width: 100%;
height: 100%;
}
#container {
position: absolute;
top: 25px;
left: 50px;
right: 50px;
bottom: 25px;
overflow: hidden;
z-index: 1;
}
#overlap {
background-color: green;
position: absolute;
height: 100%;
width: 250px;
overflow: hidden;
right: 0;
z-index: 10;
}
</style>
</head>
<body>
<div id="container">
<iframe height="100%" width="100%" src="Test.docx"></iframe>
</div>
<div id="overlap">
</div>
</body>
</html>
