我正在尝试构建一个页面教程的东西,其中div在页面上突出显示。我有一个模态对话框,通常显示在叠加层的顶部。但是,我想要做的是将模态对话框置于叠加层后面,但将该模态中的特定div放到前面。
Here is a JS fiddle of my code
如何让div显示在叠加层顶部?
CSS:
.overlay
{
position:fixed;
top:0;
left:0;
right:0;
bottom:0;
z-index:1000;
background-color:#000000;
opacity:0.7;
}
.modal
{
position:absolute;
top:300px;
left:50%;
z-index:999;
overflow:auto;
margin:-250px 0px 0px -280px;
border:1px solid #999;
background-color:#fff;
border-radius:6px;
-webkit-border-radius:6px;
-moz-border-radius:6px;
-webkit-box-shadow:0 3px 7px rgba(0,0,0,0.3);
-moz-box-shadow:0 3px 7px rgba(0,0,0,0.3);
box-shadow:0 3px 7px rgba(0,0,0,0.3);
background-clip:padding-box;
padding:10px;
}
.highlight
{
z-index:1002;
position:relative;
background-color:#ffffff;
}
.modal-contents
{
height:100px;
min-width:100px;
}
.section
{
padding:5px;
}
HTML:
<body>
<div class="overlay"></div>
<div class="modal">
<h1>Modal Window</h1>
<div class="modal-contents">
<div class="section highlight">
This div should be highlighted above the overlay!
</div>
<div class="section">
This is section two
</div>
</div>
</div>
</body>
