Let's say I have
<div class="myDiv">Hi there</div>
I want to put a background-image and give it an opacity of 0.5 – but I want that the text I have written will have full opacity (1).
If I would write the CSS like this
.myDiv { opacity:0.5 }
everything will be in low opacity – and I don't want that.
So my question is – How can I get low-opacity background image with full opacity text?
This question is related to
html
css
background
background-image
So here is an other way:
background-image: linear-gradient(rgba(255,255,255,0.5), rgba(255,255,255,0.5)), url("your_image.png");
div {
width: 200px;
height: 200px;
display: block;
position: relative;
}
div::after {
content: "";
background: url(image.jpg);
opacity: 0.5;
top: 0;
left: 0;
bottom: 0;
right: 0;
position: absolute;
z-index: -1;
}
<div> put your div content</div>
<!DOCTYPE html>
<html>
<head></head>
<body>
<div style=" background-color: #00000088"> Hi there </div>
<!-- #00 would be r, 00 would be g, 00 would be b, 88 would be a. -->
</body>
</html>
including 4 sets of numbers would make it rgba, not cmyk, but either way would work (rgba= 00000088, cmyk= 0%, 0%, 0%, 50%)
I implemented Marcus Ekwall's solution but was able to remove a few things to make it simpler and it still works. Maybe 2017 version of html/css?
html:
<div id="content">
<div id='bg'></div>
<h2>What is Lorem Ipsum?</h2>
<p><strong>Lorem Ipsum</strong> is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen
book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with
desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.</p>

</section> None of the solutions worked for me. If everything else fails, get the picture to Photoshop and apply some effect. 5 minutes versus so much time on this...
This can be done by using the different div class for the text Hi There...
<div class="myDiv">
<div class="bg">
<p> Hi there</p>
</div>
</div>
Now you can apply the styles to the
tag. otherwise for bg class. I am sure it works fine
