问题描述
是否可以将子元素(C)放在其父元素(B)之下,以及B的邻居(C)之上?
描述起来有点困难,您可以观看示例
HTML:
< div class = red>< / div>
< div class = green>< / div>
< div class = blue>< / div>
CSS:
.red {
background-color:红色;
高度:500像素;
宽度:500像素;
z-index:1;
}
.green {
background-color:green;
宽度:300像素;
高度:300像素;
头寸:固定;
top:0像素;
左:0px;
z-index:3;
}
.blue {
background-color:blue;
宽度:100像素;
高度:100像素;
头寸:固定;
top:0像素;
左:250像素;
z-index:2;
}
Is it possible to position child element (C) under its parent (B), and above B's neighbor (C)?
It's a little bit difficult to describe, you can watch example here.
The question is to position blue div.inner
above red div.neighbor
AND under green div.outer
.
To illustrate:
HTML code:
<div class="neighbor"> </div>
<div class="outer">
<div class="inner"></div>
</div>
CSS code:
.neighbor{
background-color: red;
height: 500px;
width: 500px;
}
.outer{
background-color: green;
width: 300px;
height: 300px;
position: fixed;
top: 0px;
left: 0px;
}
.inner{
background-color: blue;
width: 100px;
height: 100px;
position: fixed;
top: 0px;
left:250px;
}
