In this post I am going to share simple CSS code snippet to Change Image on Hover. If you are looking to add swap image feature while visitor hover on any image then this pure CSS code is for you. You can easily integrate this code snippet in your web based project and apply Change Image on Hover effect to display front and back part of image.
Change Image on Hover


HTML

Here we use HTML5 figure element and place image front and back part.

<figure class="swap-on-hover">
 <img  class="swap-on-hover__front-image" src="https://c402277.ssl.cf1.rackcdn.com/photos/1620/images/carousel_small/bengal-tiger-why-matter_7341043.jpg?1345548942"/>
  <img class="swap-on-hover__back-image" src="http://www.menucool.com/slider/jsImgSlider/images/image-slider-2.jpg"/>
</figure>


CSS

Now adding CSS and making your images changeable while hover. By default image front look will display and when ever you hover on image you can display back part of image.

body {
    background-color: orange;
    margin: 50px auto;
    box-sizing: border-box;
}
 
/* Make the container relative */
.swap-on-hover {
  position: relative;   
    margin:  0 auto;
    max-width: 400px;
}
 
/* Select the image and make it absolute to the container */
.swap-on-hover img {
  position: absolute;
  top:0;
  left:0;
    overflow: hidden;
    /* Sets the width and height for the images*/
    width: 400px;
    height: 400px;
}
 
/* 
    We set z-index to be higher than the back image, so it's alwyas on the front.
 
We give it an opacity leaner to .25s, that way when we hover we will get a nice fading effect. 
*/
.swap-on-hover .swap-on-hover__front-image {
  z-index: 9999;
  transition: opacity .5s linear;
  cursor: pointer;
}
 
/* When we hover the figure element, the block with .swap-on-hover, we want to use > so the front-image is going to have opacity of 0, which means it will be hidden, to the back image will show */
.swap-on-hover:hover > .swap-on-hover__front-image{
  opacity: 0;
}
