发下代码看看,不然不好说
设置z-index的值,http://www.w3school.com.cn/css/pr_pos_z-index.asp
hello
hello
test
hello2
test2
上面的test能够透过背景色看到。
position:relative;
定位可以吧,在两个style都加上这个
<div style=" border:1px solid red; width:50px; position:absolute ; background-color: gray; z-index:10; " > hello<br/> hello<br/>test </div><div style=" border:1px solid green; width:50px;position:absolute; background-color: yellow; z-index:0; top:30px; " >hello2<br></br>test2</div>
position改成absolute以后就可以用z-index设置它了,z-index越大 ,离用户越近
