HTML background opacity no to affect the foreground - html

I have an image for my background that has an opacity on .4. I have an image in front of it that seems have the same opacity. What do I do so the opacity of the front image is 1.0?
Here is a jsfiddle.

Here is my html
<div>Hello World
<img src="http://i.dailymail.co.uk/i/pix/2013/11/11/article-2500617-007F32C500000258-970_306x423.jpg" alt="">
</div>
and my css
div{
width : auto;
height : 1000px;
background-image : url("http://i.dailymail.co.uk/i/pix/2013/11/11/article-2500617-007F32C500000258-970_306x423.jpg");
background-position: 65% 65%;
background-repeat: no-repeat;
background-size: cover;
opacity: .4;
}

you can give div position relative and use before with same image and give before same opacity.
you can check below given code within jsfiddle.
/* Here is the code Start */
div{
width : auto;
height : 1000px;
position:relative;
}
div:before{
content:" ";
position:absolute;
width:100%;
height:100%;
top:0;
left:0;
background-image : url("http://i.dailymail.co.uk/i/pix/2013/11/11/article-2500617-007F32C500000258-970_306x423.jpg");
background-position: 65% 65%;
background-repeat: no-repeat;
background-size: cover;
opacity: 0.4;
}
/* Here is the code Start */

I found a solution. You need to put your background image in the div::after pseudo element, like this :
div{
width : auto;
height : 1000px;
}
div::after {
content: "";
background-image : url("http://i.dailymail.co.uk/i/pix/2013/11/11/article-2500617-007F32C500000258-970_306x423.jpg");
opacity: 0.5;
top: 0;
left: 0;
bottom: 0;
right: 0;
position: absolute;
z-index: -1;
background-position: 65% 65%;
background-repeat: no-repeat;
background-size: cover;
}
Like this, the div element doesn't have the transparent opacity, which was previously applied to its child element, the image.
I updated your fiddle

How to add an image as a text background using CSS pseudo element (:after)

Is it possible to use a pseudo-element as a background for an HTML text element (h1)?
I know that the simple way of using an image as a text background is using the background-clip: text; property directly, but in my case, I need to apply some additional css properties to the background image (rotation and maybe some filter properties as well), and because of this, I cannot apply those css properties directly, as they will be applied to the text element as well.
I think that :after pseudo element can do this, but I don't have any success.
Let's say that this is my h1 wrapped in a div:
<div class="wrapper">
<h1>My title that should have an image background</h1>
</div>
And this is the css I've tried:
.wrapper {
width: 100vw;
height: 400px;
}
.wrapper h1 {
position: relative;
-webkit-background-clip: text;
-webkit-text-fill-color: transparent;
}
.wrapper h1:after {
content: '';
position: absolute;
background-image: url(https://picsum.photos/200);
background-position: 50% 50%;
background-repeat: no-repeat;
transform: rotate(-3deg); /* the image is required to be rotated */
background-size: cover;
left: 0;
top: 0;
width: 100%;
height: 100%;
}
https://jsfiddle.net/8ztcuv12/
The expected resultL
Is there a better way of achieving this? Any solutions are welcome.
You can use backround-image on wrapper so that if you want to rotate heading.
It don't rotate image too.
.wrapper {
width: 100vw;
height: 100px;
position: relative;
}
.wrapper h1 {
transform: rotate(-3deg);
}
.wrapper:after {
content: '';
position: absolute;
background-image: url(https://picsum.photos/200);
background-position: 50% 50%;
background-repeat: no-repeat;
transform: rotate(-3deg);
/* the image is required to be rotated */
background-size: cover;
left: 0;
top: 0;
width: 100%;
height: 100%;
z-index: -1;
}
<div class="wrapper">
<h1>My title that should have an image background</h1>

How to set opacity or decrease brightness to div's background-image using CSS

In the following example only background-color displays but the image is not visible. The opacity also seems to be not working.
.my-container {
position: relative;
background-color: blue;
min-height: 100px;
}
.my-container:before {
content: '';
display: block;
position: absolute;
left: 0;
top: 0;
width: 100%;
height: 100%;
z-index: 1;
opacity: 0.1;
background-image: url("https://hips.hearstapps.com/hmg-prod.s3.amazonaws.com/images/golden-retriever-dog-royalty-free-image-505534037-1565105327.jpg");
background-position: 100% center;
background-repeat: no-repeat;
-ms-background-size: cover;
-o-background-size: cover;
-moz-background-size: cover;
-webkit-background-size: cover;
background-size: cover;
}
<div class="my-container">
<p>Contents</p>
<div>
Your code actually works and image is visible, but you set opacity: 0.1 and background: blue so it's barely visible. Just increase the opacity and maybe change background-color to more user friendly.
I cleaned up your code and placed content on top of image. In your example content has on image overlay which makes text harder to see.
.my-container {
position: relative;
background: blue;
height: 200px;
font-size:2rem;
color:#fff;
}
.my-container:before {
content: '';
position: absolute;
top:0;
right:0;
bottom:0;
left:0;
opacity: 0.6;
background-image: url("https://hips.hearstapps.com/hmg-prod.s3.amazonaws.com/images/golden-retriever-dog-royalty-free-image-505534037-1565105327.jpg");
background-position:center;
background-repeat: no-repeat;
background-size: cover;
}
#content{
position:absolute;
top:0;
right:0;
bottom:0;
left:0;
z-index:1;
}
<div class="my-container">
<div id="content">CONTENT</div>
<div>
It seemed to work just fine for me. I can see the picture when I set opacity: 0.5; And the blue background is still there. So I would suggest just raise your opacity
higher than 0.1. And see what looks best for you.
Please use the css filter: brightness(80%); instead of opacity.
filter: brightness(50%);

How to zoom in a background image to the center of it

How do I zoom in a high quality image, for instance 2000px x 2000px, to the center of a container ? I've tried using transform: scale () but it still makes it scrollable vertically or horizontally. I'm specifically looking for a mobile version. How do I make the image zoomed in centered exactly according to the width of mobile? Using width: 100% doesn't help either. And if I define it like in the code below using pixels it is cropped out on mobile. Do I make it exactly width and height or mobile or? I need it to fully cover whole body and be zoomed in exactly in the center of image. Thanks for you answers. Also zoomed quality is really bad even though it is high quality image.
Basically center and zoom this image so that on mobile it will cover whole screen, spin and look like this:
body {
padding:0;
margin:0;
width: 100%;
height: 100%;
}
#wrap {
transform: scale(2.0);
}
#bg {
width: 1400px;
height: 1400px;
background: url(bg.png);
background-size: contain;
background-position: center center;
-webkit-animation: rotation 9s infinite linear;
}
I have been playing around with this a bit. This is what I ended up with.
Here is the logic that I used figuring this out:
An image rotates around its center.
If I put the image in a container it will cut a part of the image off. The image will still rotate around the center of the image....But that is not the center of the container anymore.
Solution: I made the image behave like background: cover; by using min-width: 100%; and min-height: 100%;
Solution: I centered the image in the container using flexbox.
Another way of centering might be preferable, since the flexbox also affects other children of the container. So any improvements/comments about that would be welcome :).

Hope it helps :)
Set width: 100% and remove background-size: contain:
JSFiddle
#bg {
width: 100%;
height: 500px;
background: url(http://placehold.it/1000x1000);
background-position: center;
background-repeat: no-repeat;
}
<div id="bg"></div>
and if you want to use these styles for the body, add background-attachment: fixed:
JSFiddle
body {
padding:0;
margin:0;
width: 100%;
height: 100%;
background: url(http://placehold.it/1000x1000);
background-position: center;
background-repeat: no-repeat;
background-attachment: fixed;
}
You could use background-size: 200% combined with background-position: -50%, -50% or a similar proportion (300% size vs. -100% position offset)
Example:
.x {
width: 400px;
height: 300px;
margin: 100px;
background: url(http://placehold.it/400x400/fa0);
background-size: 300%;
background-position: -100%, -100%;
}
<div class="x">
</div>
About rotation: You can rotate the whole thing, but not the background image alone, so you have to use two DIVs: Put one rotating div into another (smaller) div that has overflow: hidden.The rotating DIV has to have position: absolute and z-index: -1 to remain in the background.
Here's that situation in action:
.y {
width: 400px;
height: 300px;
margin: 100px;
overflow: hidden;
position: relative;
}
.x {
position: absolute;
width: 800px;
height: 600px;
left: -200px;
top: -100px;
z-index: -1;
background: url(http://placehold.it/400x400/fa0);
background-size: 300%;
background-position: -100%, -100%;
animation: move 5s infinite linear;
}
#keyframes move {
100% {transform: rotate(360deg);}
}
<div class="y">
Any content here.
<div class="x">
</div>

how does one put a background on a floating element in css3 and change it's opacity?

In the css I have a few images in the style folder so ignore the other images that don't show up. The floating element leftpara and joinbutton(eventhough it's a para not the button) have background white and i want to give it an opacity of .4.
#stuff:before{
display: block; content:""; position: absolute; z-index:-1;
background: url(blah.jpg);
opacity:.3;
top:10%; left: 0; right: 0;
height: 50%;
}
fiddle
You can try this code:
withhsla(0,0%,100%,0.70) or rgba you use a white background with whatever percentage saturation or opacity to get the look you desire.
and you can use filter: alpha(opacity=50); to get the opacity
background-attachment: fixed;
background-image: url(blah.jpg);
display: block;
position: absolute;
left: 0;
top: 0;
width: 100%;
height: 100%;
z-index: 1;
background-color: hsla(0,0%,100%,0.70);
background-blend-mode: overlay;
background-repeat: no-repeat;
filter: alpha(opacity=50);
Your question is slightly vague, however the following code applies "a background on a floating element in css3 and changes its opacity?
div{
float: right;
display:block;
width: 350px;
height: 150px;
background-image: url(http://placehold.it/350x150/ff0000/ffffff);
opacity: 0.5;
}

Background Image opacity in CSS (working in dreamweaver)

Working in Dreamweaver, I'm trying to get a background image that is the same on every page. I want it to be set and fill the whole page, have content scroll not the picture, and I need the picture to be a bit transparent, so the text will be easier to read. I have NO idea how to do opacity other than that this is what I have in my Style.css class.
body {
overflow-x: hidden;
width: 100%;
background-image:
url(/CuzbZDV%5B1%5D.jpg);
background-repeat: no-repeat;
background-position: top center;
background-attachment: fixed;
}
Try with that:
body:before {
position: fixed;
z-index: -1;
content: " ";
top: 0; left: 0; right: 0; bottom: 0;
background: url() no-repeat center center fixed;
background-size: cover;
opacity: .5;
filter: alpha(opacity=50); /* IE8, I believe... */
}
