问题描述
我希望 div1
高于 div2
。我尝试使用 z-index
但它不起作用。
我试过这段代码:
div {width:100px; height:100px;}。div1 {background:red; z-index:1;}。div2 {background:blue; margin-top:-15vh; z-index:2}
< div class = div1>< / div>< div class =div2>< / div>
解决方案
您可以向两个div添加 position:relative
并创建 堆叠上下文
div {width:100px; height:100px;}。div1 {background:red; z-index:2; position:relative;}。div2 {background:blue; margin-top:-15vh; z-index:1; position:relative;}
< div class =div1 >< / div>< div class =div2>< / div>
b
$ b
或者您可以使用 transform-style:preserve-3d;
现在 .div1
应该位于 3D
div {width:100px; height:100px;}。div1 {background:red; z-index:2; transform-style:preserve-3d;}。div2 {background:blue; margin-top:-15vh; z-index:1;}
< div class = div1>< / div>< div class =div2>< / div>
您也可以随意使用 transform
,例如 translate
或 rotate
$ b
div {width:100px; height:100px;}。div1 {background:red; z-index:2; transform:translate(1px);}。div2 {background:blue; transform:translate(1px,-15vh); z-index:1;}
< div class = div1>< / div>< div class =div2>< / div>
div {width:100px; height:100px;}。div1 {background:red;过滤器:亮度(0.4); z-index:2;}。div2 {background:blue; margin-top:-15vh;过滤器:亮度(0.4); z-index:1;}
< div class = div1>< / div>< div class =div2>< / div>
I want the div1
to be above div2
. I try with z-index
but it does not work.
I've tried this code:
div {
width: 100px;
height: 100px;
}
.div1 {
background: red;
z-index: 1;
}
.div2 {
background: blue;
margin-top: -15vh;
z-index: 2
}
<div class="div1"></div>
<div class="div2"></div>
解决方案
You can add position: relative
to both divs and create stacking context
div {
width:100px;
height: 100px;
}
.div1 {
background: red;
z-index: 2;
position: relative;
}
.div2 {
background: blue;
margin-top: -15vh;
z-index: 1;
position: relative;
}
<div class="div1"></div>
<div class="div2"></div>
Or you could use transform-style: preserve-3d;
so now .div1
should be positioned in the 3D-space and not flattened in the plane.
div {
width:100px;
height: 100px;
}
.div1 {
background: red;
z-index: 2;
transform-style: preserve-3d;
}
.div2 {
background: blue;
margin-top: -15vh;
z-index: 1;
}
<div class="div1"></div>
<div class="div2"></div>
You can also use some random transform
like translate
or rotate
div {
width:100px;
height: 100px;
}
.div1 {
background: red;
z-index: 2;
transform: translate(1px);
}
.div2 {
background: blue;
transform: translate(1px, -15vh);
z-index: 1;
}
<div class="div1"></div>
<div class="div2"></div>
Filters
also work but they have bad Support
div {
width:100px;
height: 100px;
}
.div1 {
background: red;
filter: brightness(0.4);
z-index: 2;
}
.div2 {
background: blue;
margin-top: -15vh;
filter: brightness(0.4);
z-index: 1;
}
<div class="div1"></div>
<div class="div2"></div>
