Css Solutions
Solution 1 - Css
I know this is old, but just in case it will help someone else.
<div style="background-color: rgba(255, 0, 0, 0.5)">child</div>
Where rgba
is: red, green, blue, and a
is for transparency.
Solution 2 - Css
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;
}

Solution 3 - Css
You can do it with pseudo-elements: (demo on dabblet.com)
your markup:
<div class="parent">
<div class="child"> Hello I am child </div>
</div>
css:
.parent{
position: relative;
}
.parent:before {
z-index: -1;
content: '';
position: absolute;
opacity: 0.2;
width: 400px;
height: 200px;
background: url('http://img42.imageshack.us/img42/1893/96c75664f7e94f9198ad113.png') no-repeat 0 0;
}
.child{
Color:black;
}
Solution 4 - Css
As mentioned by Tom, background-color: rgba(229,229,229, 0.85)
can do the trick.
Place that on the style of the parent element and child wont be affected.
Solution 5 - Css
You can't. Css today simply doesn't allow that.
The logical rendering model is this one :
> If the object is a container element, then the effect is as if the contents of the container element were blended against the current background using a mask where the value of each pixel of the mask is
Reference : css transparency
The solution is to use a different element composition, usually using fixed or computed positions for what is today defined as a child : it may appear logically and visualy for the user as a child but the element doesn't need to be really a child in your code.
A solution using css : fiddle
.parent {
width:500px;
height:200px;
background-image:url('http://canop.org/blog/wp-content/uploads/2011/11/cropped-bandeau-cr%C3%AAte-011.jpg');
opacity: 0.2;
}
.child {
position: fixed;
top:0;
}

Solution 6 - Css
I had the same problem and I fixed by setting transparent png image as background for the parent tag.
This is the 1px x 1px PNG Image that I have created with 60% Opacity of black background !
Solution 7 - Css
You can't do that, unless you take the child out of the parent and place it via positioning.
The only way I know and it actually works, is to use a translucid image (.png with transparency) for the parent's background. The only disavantage is that you can't control the opacity via CSS, other than that it works!
