I've got a background which needs to have a dark background like it's got a low brightness.
When I add my brightness to 80% it's perfect but then I also lose the brightness of my text which is overlayed and that decreases in brightness as well. Is there a way I can increase the brightness on the text?
background-image: url("https...);
background-position: 50% 50%;
background-size: cover;
padding: 100px;
filter: brightness(80%);
in this case ::before or ::after is solution
div {
width: 100%;
height: 200px;
font-size: 40px;
font-weight: bold;
color: #fff;
position: relative;
}
span {
position: relative;
z-index: 1;
}
div::before {
content: '';
position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;
filter: brightness(80%);
background-image: url("https://images-na.ssl-images-amazon.com/images/I/41-SYJSrDgL.jpg");
background-position: 50% 50%;
background-size: cover;
z-index: 0;
}
<div><span>test<span></div>

I am trying to make a nice background with an image but I want the image repeated to fill the screen, with opacity set to 0.5 and it rotated 45 degrees. I have tried a number of things to accomplish this but have had no luck. Anyone have any ideas?
In this Codepen, I have the image rotated and opaque but cannot get background-repeat to work.
.background {
height: 500px;
width: 500px;
position: relative;
display: inline-block;
padding: 100px;
border: black 3px solid;
}
.background::before {
content: "";
position: absolute;
overflow: hidden;
width: 100px;
height: 100px;
left: 0;
top: 0;
z-index: -1;
opacity: 0.5;
background: url(https://cambridgewords.files.wordpress.com/2019/11/funny.jpg);
background-size: contain;
transform: rotate(45deg);
background-repeat: repeat;
opacity: 0.5;
}
<span class='background'>HElloWorld</span>
You can do it like below:
.background {
height: 500px;
width: 500px;
position: relative;
z-index:0;
display: inline-block;
overflow:hidden; /* hide the overflow here not on the pseudo element */
padding: 100px;
border: black 3px solid;
}
.background::before {
content: "";
position: absolute;
z-index: -1;
/* 141% ~ sqrt(2)x100% to make sure to cover all the area after the rotation */
width: 141%;
height:141%;
/**/
/* to center*/
left: 50%;
top: 50%;
/* */
background: url(https://cambridgewords.files.wordpress.com/2019/11/funny.jpg);
background-size: 100px 100px; /* size of the image*/
transform:translate(-50%,-50%) rotate(45deg); /* center the element then rotate */
opacity: 0.5;
}
<span class='background'>
HElloWorld
</span>
Try increasing the size of the ::before pseudo-element, and then decreasing the background size like this:
.background::before {
content: "";
position: absolute;
overflow: hidden;
width: 100%; /* made width 100% */
height: 100%; /* made height 100% */
left: 0;
top: 0;
z-index: -1;
opacity: 0.5;
background: url(https://cambridgewords.files.wordpress.com/2019/11/funny.jpg);
background-size: 100px; /* made background size smaller */
transform: rotate(45deg);
background-repeat: repeat;
opacity: 0.5;
}
This just makes the background pseudo-element the full size of the element, and then makes the background small and repeating. I hope this helps.
How to create a partial width opacity ?
I have a div that has a background image with transparency, I used after to do get the effect like this
.indicators-menu {
width: 100%;
height: 100%;
display: block;
position: absolute;
top: 0;
z-index: 1;
}
.indicators-menu::after {
background-image: url('bg_platform_repeat.jpg');
content: "";
opacity: 0.9;
top: 0;
position: absolute;
z-index: -1;
left: 0;
width: 100%;
height: 100%;
background-repeat: no-repeat;
background-size: cover;
background-position: unset;
}
This works great, but what I need to do is to split the opacity by width
instead of 100% to 80% with opacity 0.9 and 20% with opacity 1
I thought to use the CSS mask property but I see that its not well supported
what i need to do is to split the opacity by width instead of 100% to 80% with opacity 0.9 and 20% with opacity 1
Use two pseudo-elements with the same background image but position them differently.
div {
width: 460px;
height: 300px;
margin: 1em auto;
border: 1px solid red;
position: relative;
}
div:before,
div:after {
content: "";
position: absolute;
top: 0;
left: 0;
bottom: 0;
background-image: url(http://www.fillmurray.com/460/300);
background-repeat: no-repeat;
background-size: cover;
}
div:before {
width: 80%;
opacity: 0.5;
/* for example */
}
div:after {
width: 20%;
left: 80%;
background-position: 100% 0;
}
<div>
</div>
One idea is to use an overlay above the image to simulate this effect. The color used need to be the same as the below background:
.box {
background:
linear-gradient(rgba(255,255,255,0.3),rgba(255,255,255,0.3)) left/80% 100%,
url('https://picsum.photos/200/200?image=1069') center/cover;
background-repeat: no-repeat;
width: 200px;
height: 200px;
}
<div class="box">
</div>
Use :before with background: white; and opacity:0.1(I set 0.4 only you to see the difference) and width:80%
.indicators-menu::after,.indicators-menu::before{
background-image: url('https://i.imgur.com/BK7wL0d.jpg');
content: "";
opacity:1;
top: 0;
position: absolute;
z-index: -1;
left: 0;
width: 100%;
height: 100%;
background-repeat: no-repeat;
background-size: cover;
background-position: unset;
}
.indicators-menu::before{
background: white;
opacity: 0.4;
z-index: 2;
width: 80%;
}
<div class="indicators-menu">
</div>
I have a background image set on the .section class in CSS. On that, I have an opacity as well. My child img is a transparent png however it's showing behind the background image on the div and it's also inheriting the opacity i have on the background image. How can I bring this to the top? I tried using z-indexes but it was not solving it.
.section {
background-size: 100%;
background-color: rgba(0, 0, 0, 0.5);
background-image: url(/image/bg.png);
background-repeat: no-repeat;
position: relative;
}
.section:before {
content: "";
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
background-image: linear-gradient(to bottom right, #000000, #000000);
opacity: 0.6;
}
.logo {
width: 100%;
}
<div class="section">
<img class="logo" src={ "imgafi2x.png"}/>
</div>
Just using the below code:
Note: I didn't add snippet because it was React & SCSS. Stack Snippets don't support both React & SCSS. That's the reason I have linked to JSBin.
.section {
background-size: 100%;
background-color: rgba(0,0,0,0.5);
background-image: url(//placehold.it/500?text=BG);
background-repeat: no-repeat;
position:relative;
&:before {
content: ' ';
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
background-image: linear-gradient(to bottom right,#000000,#000000);
opacity: .6;
z-index: 1;
}
.logo {
width: 100%;
position: relative; /* Change Here */
z-index: 2; /* Change Here */
}
}

I have a background which fills the screen, when I get to 1234px I want to position the background image a little more to the left and a little bit further down, but when I use background-position to offset like this :-
background-position: right 20px bottom 40px;
I get whitespace where it is pushing the background away. Is there a way to resolve this? Here is my css class:-
.full-background{
height:100vh;
width:100%;
background: no-repeat;
background-position: bottom center;
background-origin: content-box;
background-size: cover;
background-image: url('assets/img/background.png');
min-width:100%;
position:relative;
}
You could use a pseudo element, like this
.bkg {
position: absolute;
left: 0;
top: 0;
right: 0;
bottom: 0;
overflow: hidden;
}
.bkg::after {
content: '';
position: absolute;
left: -10%;
top: -10%;
width: 120%;
height: 120%;
background-image: url(http://lorempixel.com/500/400/nature/1);
background-size: cover;
background-position: center;
}
#media screen and (min-width: 900px) { /* add your min-width here */
.bkg::after {
left: calc(-10% + 20px);
top: calc(-10% + 40px);
}
}
<div class="bkg"></div>
I've been using that code on my body, to get a full background with some mi-transparent white background on it :
body {
background: url('../images/bg.jpg') no-repeat center center fixed;
padding-top: 50px;
}
body::after {
content: "";
background: white;
opacity: 0.5;
top: 0;
left: 0;
bottom: 0;
right: 0;
position: absolute;
z-index: -1;
}
The problem is that the white background doesn't go lower than the screen size as you can see here. Any idea how to fix that ?
It's because body::after isn't fixed, change the css like this :
body::after {
content: "";
background: white;
opacity: 0.5;
top: 0;
left: 0;
bottom: 0;
right: 0;
position: fixed;
z-index: -1;
}
Here is an example with a black background
Instead of using a ::before or ::after pseudo element, you can use css multple backgrounds.
Generate the base64 from this site: http://px64.net/
Apply the background to the body element.
#foo {
width: 400px;
height: 150px;
visibility: visible;
}
#foo {
background: url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAADUlEQVR42mNgYPhfDwACggF/yWU3jgAAAABJRU5ErkJggg==) repeat, url(http://www.openkorat.com/wp-content/uploads/2015/08/extra-bg-green.jpg) no-repeat;
background-size: auto, cover;
}
<div id="foo"></div>
Make the ::after element position: fixed.
Fiddle
body {
background: url('../images/bg.jpg') no-repeat center center fixed;
padding-top: 50px;
}
body::after {
content: "";
background: red;
opacity: 0.5;
top: 0;
left: 0;
bottom: 0;
right: 0;
position: fixed;
z-index: -1;
}
div {
height: 800px;
}
<div>div</div>
