I have a list of organization logos on a web page. Most of them use a couple of different colors. I would like to show the silhouette of the logos, and only reveal the real colors on hover.
body {
background: deeppink;
}
img {
filter: brightness(0) invert(1);
}
img:hover {
filter: none;
}
<img src="https://upload.wikimedia.org/wikipedia/commons/thumb/e/ef/Stack_Overflow_icon.svg/240px-Stack_Overflow_icon.svg.png" />
I can make the logos white with the code above, but I would like to make them pink. And not just any pink, I would like to use a specific color code.
I have tried to add the hue-rotate() function, but the logos are still white. I guess it's because of the brightness level.
Any ideas?
EDIT: More precise code
It's not an optimal solution, but adding opacity will work, if the background itself is the same color as you want for the silhouette.
body {
background: deeppink;
}
img {
filter: brightness(0) invert(1);
opacity: 0.8;
}
img:hover {
filter: none;
opacity: 1;
}
<img src="https://upload.wikimedia.org/wikipedia/commons/thumb/e/ef/Stack_Overflow_icon.svg/240px-Stack_Overflow_icon.svg.png" />

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 ?
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.
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>
DEMO
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.
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%)}
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>
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%);
}
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);}
-webkit-filter: brightness(0.50);
I've got this cool solution:
https://jsfiddle.net/yLcd5z0h/
try this if you need to convert black image into white:
.classname{
filter: brightness(0) invert(1);
}
Like
.classname
{
opacity: 0.5;
}
When I'm hovering the image I would like it to turn black. The image is gray by default.
img:hover {
filter: grayscale(100%) brightness(1.6) saturate(2) contrast(150);
}
<img src="https://i.stack.imgur.com/wpQiz.png">
Use the invert filter and you will get closer:
img:hover {
filter: invert(1);
}
<img src="https://i.stack.imgur.com/wpQiz.png" >
Or simply brightness(0)
img:hover {
filter: brightness(0);
}
<img src="https://i.stack.imgur.com/wpQiz.png" >
Why not think the other way around, use a black image and change the visual with opacity levels?
img {
width: 100px;
height: auto;
opacity: .5;
transition: opacity .25s;
}
img:hover {
opacity: 1;
}
<img src="https://i.stack.imgur.com/Eo3De.png">
Could not the following be done? (you would need 2 separate images though, one gray and one colored black)
<img src='../img/badge/graydot.png' onmouseover="this.src='../img/badge/blackdot-hover.png';" onmouseout="this.src='../img/badge/graydot.png';" />
Is there any way to change the color of an img (not background) using css?
I mean there is an image and on hover I want to say darken it, best way to do it? And yes is it possible without using opacity?
You could use CSS3 filters, like this:
img:hover {
-webkit-filter: brightness(.5);
filter: brightness(.5);
}
For more compatibility infos - CSS filters
You can use CSS filters, example:
Change saturation:
-webkit-filter: hue-rotate(270deg);
or change the brightness:
-webkit-filter: brightness(.5);
Example:
http://jsfiddle.net/m9sjdbx6/3/
http://jsfiddle.net/m9sjdbx6/4/
<img src="http://2.bp.blogspot.com/-hAOQ_DrZM1E/Ub6s63_iqxI/AAAAAAAC9hc/2mfBJjeQNos/s1600/Blind+Chess-Board.jpg"></img>
Saturation (color):
img:hover {
-webkit-filter: hue-rotate(270deg);
}
Brightness:
img:hover {
-webkit-filter: brightness(0.2);
}
It is quite common to want certain images to be lit up (increase brightness) when your mouse pointer hovers over them.
One technique that I know of, that works on white backgrounds is to reduce opacity on hover, which in effect increases brightness by letting more white through. The problem is obviously that it will only work on a white background.
Is there any CSS that I can add to my images that will either
a. Add a white background to the images which fits exactly, so that the same light-up effect will take place on any color background, or
b. Achieve the same effect without adding white backgrounds or using opacity at all
encapsule your image with a div
<div class="brightness">
<img src="test.jpg">
</div>
and apply the good css :
.brightness {
background-color: white;
display: inline-block;
}
.brightness img:hover {
opacity: .5;
}
fiddle: http://jsfiddle.net/5yush/
image:hover { filter: brightness(50%); }
Add this class to any image
.image-hover-highlight {
-webkit-transition: all 0.50s;
transition: all 0.50s;
&:hover {
border: 1px solid gray;
filter: brightness(130%);
-webkit-filter: brightness(130%);
-moz-filter: brightness(130%);
-o-filter: brightness(130%);
-ms-filter: brightness(130%);
-webkit-transition: all 0.50s;
transition: all 0.50s;
}
}
would something like this work for you? http://jsfiddle.net/omegaiori/teAP7/1/
in order to have this working you have to wrap your image in a div
.img-cont {
background:white;
box-sizing:border-box;
-moz-box-sizing:border-box;
-webkit-box-sizing:border-box;
margin:30px auto 0;
width:300px;
}
and have your image width set to 100%
you can change the padding value as you wish, the box will always have the same size thanks to his box-sizing property
