问题描述
我想在父DIV中使用不透明度,但不要在DIV中使用不透明度
范例
HTML
< div class =parent>
< div class =child>
Hello I am child
< / div>
< / div>
Css
.parent {
background:url('../ images / madu.jpg')no-repeat 0 0;
}
.child {
颜色:黑色;
}
注意: > background-image in Parent Div
not Color
解决方案
如果您在:after
伪类后定义背景图片,可能会很好。这样写:
.parent {
width:300px;
height:300px;
position:relative;
border:1px solid red;
}
.parent:after {
content:'';
background:url('http://www.dummyimage.com/300x300/000/fff&text=parent+image');
width:300px;
height:300px;
position:absolute;
top:0;
left:0;
opacity:0.5;
}
.child {
background:yellow;
position:relative;
z-index:1;
}
Hey i am searching in google but i can't fine any perfect answer

解决方案
May be it's good if you define your background-image in the :after
pseudo class. Write like this:
.parent{
width:300px;
height:300px;
position:relative;
border:1px solid red;
}
.parent:after{
content:'';
background:url('http://www.dummyimage.com/300x300/000/fff&text=parent+image');
width:300px;
height:300px;
position:absolute;
top:0;
left:0;
opacity:0.5;
}
.child{
background:yellow;
position:relative;
z-index:1;
}
