CssCss Problem Overview
I want to decrease image brightness in CSS. I searched a lot but all I've got is about how to change the opacity, but that makes the image more bright. can anyone help me ?
Css Solutions
Solution 1 - Css
The feature you're looking for is filter. It is capable of doing a range of image effects, including brightness:
#myimage {
filter: brightness(50%);
}
You can find a helpful article about it here: http://www.html5rocks.com/en/tutorials/filters/understanding-css/
An another: http://davidwalsh.name/css-filters
And most importantly, the W3C specs: https://dvcs.w3.org/hg/FXTF/raw-file/tip/filters/index.html
Note this is something that's only very recently coming into CSS as a feature. It is available, but a large number of browsers out there won't support it yet, and those that do support it will require a vendor prefix (ie -webkit-filter:, -moz-filter, etc).
It is also possible to do filter effects like this using SVG. SVG support for these effects is well established and widely supported (the CSS filter specs have been taken from the existing SVG specs)
Also note that this is not to be confused with the proprietary filter style available in old versions of IE (although I can predict a problem with the namespace clash when the new style drops its vendor prefix).
If none of that works for you, you could still use the existing opacity feature, but not the way you're thinking: simply create a new element with a solid dark colour, place it on top of your image, and fade it out using opacity. The effect will be of the image behind being darkened.
Finally you can check the browser support of filter here.
Solution 2 - Css
OP wants to decrease brightness, not increase it. Opacity makes the image look brighter, not darker.
You can do this by overlaying a black div over the image and setting the opacity of that div.
<style>
#container {
position: relative;
}
div.overlay {
opacity: .9;
background-color: black;
position: absolute;
left: 0; top: 0; height: 256px; width: 256px;
}
</style>
Normal:<br />
<img src="http://i.imgur.com/G8eyr.png">
<br />
Decreased brightness:<br />
<div id="container">
<div class="overlay"></div>
<img src="http://i.imgur.com/G8eyr.png">
</div>
Solution 3 - Css
In short, place black behind the image, and lower the opactiy. You can do this by wrapping the image within a div, and then lowering the opacity of the image.
For example:
<!DOCTYPE html>
<style>
.img-wrap {
background: black;
display: inline-block;
line-height: 0;
}
.img-wrap > img {
opacity: 0.8;
}
</style>
<div class="img-wrap">
<img src="http://mikecane.files.wordpress.com/2007/03/kitten.jpg" />
</div>
Here is a JSFiddle.
Solution 4 - Css
You could use:
filter: brightness(50%);
-webkit-filter: brightness(50%);
-moz-filter: brightness(50%);
-o-filter: brightness(50%);
-ms-filter: brightness(50%);

With CSS3 we can easily adjust an image. But remember this does not change the image. It only displays the adjusted image.
See the following code for more details.
To make an image gray:
img {
-webkit-filter: grayscale(100%);
-moz-filter: grayscale(100%);
}
To give a sepia look:
img {
-webkit-filter: sepia(100%);
-moz-filter: sepia(100%);
}
To adjust brightness:
img {
-webkit-filter: brightness(50%);
-moz-filter: brightness(50%);
}
To adjust contrast:
img {
-webkit-filter: contrast(200%);
-moz-filter: contrast(200%);
}
To Blur an image:
img {
-webkit-filter: blur(10px);
-moz-filter: blur(10px);
}

I found this today. It really helped me. http://www.propra.nl/playground/css_filters/
All you need is to add this to your css style.:
div {-webkit-filter: brightness(57%)}
Solution 7 - Css
If you have a background-image, you can do this : Set a rgba() gradient on the background-image.
.img_container {
float: left;
width: 300px;
height: 300px;
display: flex;
justify-content: center;
align-items: center;
border : 1px solid #fff;
}
.image_original {
background: url(https://i.ibb.co/GkDXWYW/demo-img.jpg);
}
.image_brighness {
background: linear-gradient(0deg, rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.5)), /* the gradient on top, adjust color and opacity to your taste */
url(https://i.ibb.co/GkDXWYW/demo-img.jpg);
}
.img_container p {
color: #fff;
font-size: 28px;
}
<div class="img_container image_original">
<p>normal</p>
</div>
<div class="img_container image_brighness ">
<p>less brightness</p>
</div>
Solution 8 - Css
You can use css filters, below and example for web-kit. please look at this example: http://jsfiddle.net/m9sjdbx6/4/
img { -webkit-filter: brightness(0.2);}
Solution 9 - Css
It's obvious that all you need to do is this
<img src="https://rb.gy/njdqof" class="IMG">
CSS follows
/*if you go lower than 100% the lighting goes dark and above 100% your lighting is brighter*/
.IMG {
filter: brightness(20%);
}
Solution 10 - Css
-webkit-filter: brightness(0.50);
I've got this cool solution: https://jsfiddle.net/yLcd5z0h/
Solution 11 - Css
try this if you need to convert black image into white:
.classname{
filter: brightness(0) invert(1);
}
Solution 12 - Css
Like
.classname
{
opacity: 0.5;
}
