Pure CSS Image Hover Zoom Solution

A minimalist CSS solution to create an image hover zoom effect for product magnification.

How to use it:

Insert an image into a DIV container:

<img alt="image" src="image.jpg" class="zoom-image">

Style the image and make it absolute positioned.

.zoom-image {
  height: 100%;
  left: 0;
  position: absolute;
  top: 0;
  -webkit-transition: all 0.25s;
  transition: all 0.25s;
  width: 100%;
  z-index: -1;
}

Add grid items as a over which will effect the zoom and location of the image when mouse hover.

<div class="grid-item"></div>
<div class="grid-item"></div>
<div class="grid-item"></div>
<div class="grid-item"></div>
<div class="grid-item"></div>
