將一個p覆蓋在另一個p上有兩種手段:一是設定margin為負值,二是設定絕對位置。

可以根個人情況設定z-index的值

1->position 為absolute的情況

<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">這裡是p1的內容          <pid="p2"></p></p></body></html>


2->用margin為負的操作

<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);}    </style></head><body><pid="p1"> 這裡是p1的內容          <pid="p2"></p></p></body></html>
