I am designing a simple webpage. I want to display a popup window in the same page just like the image attached below.
我不知道该怎么做。如果有人能给我一些代码，那就太好了。提前致谢。
以一种非常简单的方式，您可以将 z-index 属性保留在 div 的 css 中，并根据操作隐藏和显示该 div 用这个http://jsfiddle.net/b68Xb/327/ http://jsfiddle.net/b68Xb/327/

<head>
<title>LIGHTBOX EXAMPLE</title>
<style>
.black_overlay{
display: none;
position: absolute;
top: 0%;
left: 0%;
width: 100%;
height: 100%;
background-color: black;
z-index:1001;
-moz-opacity: 0.8;
opacity:.80;
filter: alpha(opacity=80);
}
.white_content {
display: none;
position: absolute;
top: 25%;
left: 25%;
width: 50%;
height: 50%;
padding: 16px;
border: 16px solid orange;
background-color: white;
z-index:1002;
overflow: auto;
}
</style>
<body>
<p>This is the main content. To display a lightbox click <a href = "javascript:void(0)" onclick = "document.getElementById('light').style.display='block';document.getElementById('fade').style.display='block'">here</a></p>
<div id="light" class="white_content">This is the lightbox content. <a href = "javascript:void(0)" onclick = "document.getElementById('light').style.display='none';document.getElementById('fade').style.display='none'">Close</a></div>
<div id="fade" class="black_overlay"></div>
</body>
