div{ background-color:red; width:200px; height:300px; left:-200px; position:relative;}这里的 position:relative 要改为 position:absolute;

div{ background-color:red; width:200px; height:300px; left:-200px; position:absolute;}span{ background-color:blue;width:20px; height:40px; position:absolute;left:200px; color:#FFF; top:75px;} 我猜你是要这种效果吧，div的position改成absolute
