There are two ways to cover one p on another p: one is to set margin to a negative value, and the other is to set absolute positioning.
You can set the z-index value based on personal circumstances
1->position is absolute
<html>
<head>
<style>
#p1{position:absolute;width:300px;height:300px;background:#ccc;}
#p2{position:absolute;left:0;top:0;width:200px;height:200px;background:red;filter:alpha(opacity=50);}
</style>
</head>
<body>
<pid="p1">这里是p1的内容
<pid="p2"></p>
</p>
</body>
</html> 2->Use operation with negative margin
<html>
<head>
<style>
#p1 {position:relative; width:300px; height:300px;background:#ccc;}
#p2 {position:relative; left:0; top:0;margin-top:-15px;width:200px; height:200px; background:red;filter:alpha(opacity=50);}
