Having trouble getting this to display correctly in my Chrome browser. I have a wrapper containing all the HTML elements, and I want to create a DIV (let's call it div-1) that includes an image with an overlay div positioned to the left, as shown in this sketch...any suggestions for quick fixes?
Here is a simple CSS solution that doesn't require an additional .wrapper div, inspired by DarkBee's approach:
.overlay {
position: relative;
}
.overlay::after {
content: " ";
z-index: 10;
display: block;
position: absolute;
height: 100%;
top: 0;
left: 0;
right: 0;
background: rgba(0, 0, 0, 0.5);
}
I have used rgba for transparency, but feel free to explore other options as well.
CSS3 allows you to create transparency without the need for custom images.
Simply include a div with the following styling:
position:absolute;
left:0;
background: rgba(255,255,255,.5);
The last value in the background property (.5) determines the level of transparency (higher values mean less transparent).
.bar {
position : relative;
}
.bar .container {
background-image : url('transparent.png');
z-index : 10;
position : absolute;
top : 0;
left : 0;
}
<div class="bar">
<img src="sample.png" />
<div class="container"> </div>
</div>
To achieve the desired effect on a division element, you can control the opacity by applying a specific class.
.opacity-control {
opacity: 0.7;
}
Similar to the previous answer, but I recommend using ::before for stacking purposes. This is especially helpful if you plan on adding text over the overlay.
.opaque {
position: relative;
}
.opaque:before {
content: " ";
z-index: 10;
display: block;
position: absolute;
height: 100%;
top: 0;
left: 0;
right: 0;
background: rgba(0, 0, 0, 0.5);
}
