本文介绍了如何在父母的子女之上定位父母的子女？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我有一个容器div，它有 background-color：red; 。这个容器大约有12个孩子，而最后一个孩子有 background-color：blue; 。我试图用 background-color：blue 将容器移动到孩子的顶部。我为容器使用了更高的Z-index，但它仍然落后于孩子。

.no1 {width：800px; height：300px;背景颜色：红色;位置：相对; z-index：999;}。no2 {position：relative;宽度：500px; height：200px;背景颜色：蓝色; z-index：1;}。no3 {position：relative;}。no4 {position：relative;}。no5 {position：relative;}

< div class =no1> < DIV> < DIV> < div class =no3> < DIV> < div class =no4> < DIV> < DIV> < DIV> < div class =no5> < div class =no2> < / DIV> < / DIV> < / DIV> < / DIV> < / DIV> < / DIV> < / DIV> < / DIV> < / DIV> < / div>< / div>

这是JSFiddle

解决方案

div>

你可以从父母中删除z-index，并给孩子一个负z-index

.no1 {width：800px;高度：300像素;背景色：红色; position：relative;}。no2 {position：relative;宽度：500像素;高度：200像素;背景色：蓝色; z-index：-1} .no3 {position：relative; } .no4 {position：relative; } .no5 {position：relative; }

< div class =no1> < DIV> < DIV> < div class =no3> < DIV> < div class =no4> < DIV> < DIV> < DIV> < div class =no5> < div class =no2> < / DIV> < / DIV> < / DIV> < / DIV> < / DIV> < / DIV> < / DIV> < / DIV> < / DIV> < / div>< / div>

I have a container div and it has background-color: red;. There are about 12 children to this container, and the last child has background-color: blue;. I tried to move the container to top of the child with background-color: blue. I used a higher z-index for the container but it is still behind the child.

.no1 { width: 800px; height: 300px; background-color: red; position: relative; z-index: 999; } .no2 { position: relative; width: 500px; height: 200px; background-color: blue; z-index: 1; } .no3 { position: relative; } .no4 { position: relative; } .no5 { position: relative; }

<div class="no1"> <div> <div> <div class="no3"> <div> <div class="no4"> <div> <div> <div> <div class="no5"> <div class="no2"> </div> </div> </div> </div> </div> </div> </div> </div> </div> </div> </div>

Here is the JSFiddle

解决方案

You could remove the z-index from the parent and give the child a negative z-index

.no1 { width:800px; height:300px; background-color:red; position:relative; } .no2 { position:relative; width:500px; height:200px; background-color:blue; z-index: -1 } .no3 { position:relative; } .no4 { position:relative; } .no5 { position:relative; }

<div class="no1"> <div> <div> <div class="no3"> <div> <div class="no4"> <div> <div> <div> <div class="no5"> <div class="no2"> </div> </div> </div> </div> </div> </div> </div> </div> </div> </div> </div>
