css可见溢出内容如何具有非透明背景,因此隐藏下面的内容?
<div class="coverer-container">
<div class="coverer">
<p>I want this to have an opaque background.</p>
</div>
</div>
<div class="coveree">
<p>So you can not see this text.</p>
</div>
.coverer-container{
position:relative;
height:0;
width:0;
overflow:visible;
}
.coverer{
position:absolute;
height:300px;
width:300px;
}
