Darken background image on hover

Question

How would I darken a background image on hover without making a new darker image?

CSS:

.image {
  background: url(\         


        

Answer 1

I would add a div around the image and make the image change in opacity on hover and add an inset box shadow to the div on hover.

img:hover{
    opacity:.5;
}
.image:hover{
    box-shadow: inset 10px 10px 100px 100px #000;
}

<div class="image"><img src="image.jpg" /></div>

Answer 2

How about this, using an overlay?

.image:hover > .overlay {
    width:100%;
    height:100%;
    position:absolute;
    background-color:#000;
    opacity:0.5;
    border-radius:30px;
}

Answer 3

Just try this code.

img:hover
{
    box-shadow: 0 25px 50px -25px rgba(0, 0, 0, .5) inset; 
    -webkit-box-shadow: 0 25px 50px -25px rgba(0, 0, 0, .5) inset; 
    -moz-box-shadow: 0 25px 50px -25px rgba(0, 0, 0, .5) inset; 
    -o-box-shadow: 0 25px 50px -25px rgba(0, 0, 0, .5) inset;
}

Answer 4

Try following code:

.image {
    background: url('http://cdn1.iconfinder.com/data/icons/round-simple-social-icons/58/facebook.png');
    width: 58px;
    height: 58px;
    opacity:0.2;
}

.image:hover{
    opacity:1;
}

Answer 5

If you have to use the current image and get a darker image then you need to create a new one. Else you can simply reduce the opacity of the .image class and the in the .image:hover you can put a higher value for opacity. But then the image without hover would look pale.

The best way would be to create two images and add the following :

.image {
    background: url('http://cdn1.iconfinder.com/data/icons/round-simple-social-icons/58/facebook.png');
    width: 58px;
    height: 58px;
    opacity:0.9;   
}
.image:hover{
    background: url('http://cdn1.iconfinder.com/data/icons/round-simple-social-icons/58/facebook_hover.png');
}
}

Answer 6

I was able to achieve this more easily than the above answers and in a single line of code by using the new Filter CSS option.

It's compatibility in modern browsers is pretty good - 95% at time of writing, though less than the other answers.

img:hover{
  filter: brightness(50%);
}

<img src='https://via.placeholder.com/300'>
