Overlay image on hover using only css

Question

I'm trying to overlay an image with a smaller image that has the background opacity of the first image when hover, using only css because i'm not able to edit the html.

Here is a sample HTML:

<div class="image">
  <a href="http://www.example.com">
    <img src="/uploads/2016/08/img1.png" class="rggclImgCenter">
  </a>
</div>

Using CSS only, i thought would be something like this:

.image:hover {
   background-image: url('https://cdn4.iconfinder.com/data/icons/ionicons/512/icon-ios7-arrow-right-128.png');
}

But it will only replace the image.

Answer 1

You could use the css pseudo element if you wouldn't like to (or cannot) modify the html.

Please be awared you cannot use :before or :after on img element

Here is the CSS:

img { max-width: 300px; } /* the image dimension */

.image a { position: relative; display: inline-block; } /* allow :before element positioning easier */
.image a:hover:before {
  position: absolute;
  top: 30px; left: 40px; /* Where to put the overlay */
  display: inline-block;
  content: ''; /* must have */
  width: 300px; height: 164px; /* size of the element */
  background-image: url('https://i.kinja-img.com/gawker-media/image/upload/s--pEKSmwzm--/c_scale,fl_progressive,q_80,w_800/1414228815325188681.jpg'); /* URL of the image */
  background-size: 300px 164px; /* Resize the image as this dimension */
  opacity: .5; /* Transparent rate */
}

Answer 2

Did not have the original image so used an image of my own. See if this helps.

You can also refer to this link: https://jsfiddle.net/askptx0y/

 .image:hover { background-image: url('https://cdn4.iconfinder.com/data/icons/ionicons/512/icon-ios7-arrow-right-128.png'); background-repeat: no-repeat; opacity: 1; } img:hover { opacity: 0.5; } 

 <div class="image"> <a href="http://www.example.com"> <img src="http://www.freedigitalphotos.net/images/img/homepage/87357.jpg" class="rggclImgCenter"> </a> </div> 

Answer 3

Try adding a :before element on :hover .

.image a:hover:before {
   content: '';
   display: block;
   position: absolute;
   background-image: url('https://cdn4.iconfinder.com/data/icons/ionicons/512/icon-ios7-arrow-right-128.png');
}

Answer 4

Make image transparency:

.image a:hover image {
   opacity: 0;
 }

Show your background image

.image a:hover {
   background-image: url('https://cdn4.iconfinder.com/data/icons/ionicons/512/icon-ios7-arrow-right-128.png');
  /* add other properties */
}

    .image:hover img {
    -webkit-filter: brightness(40%);
    -moz-filter: brightness(40%);
    -ms-filter: brightness(40%);

}
.image:hover img:after {
   content: '';
   display: block;
   position: absolute;
   background-image: url('https://cdn4.iconfinder.com/data/icons/ionicons/512/icon-ios7-arrow-right-128.png');
