Yet another lightweight jQuery code snippet to create an image gallery with zoom hover effect. It arranges the images in a grid layout and zooms the image when it clicked.

How to Create jQuery Gallery with Image Zoom Effect

Create the HTML structure for the image gallery as follows:

<div class="gallery">
  <div class="img-w">
    <img src="https://images.unsplash.com/photo-1485766410122-1b403edb53db?dpr=1&auto=format&fit=crop&w=1500&h=846&q=80&cs=tinysrgb&crop=" alt="" /></div>
  <div class="img-w"><img src="https://images.unsplash.com/photo-1485793997698-baba81bf21ab?dpr=1&auto=format&fit=crop&w=1500&h=1000&q=80&cs=tinysrgb&crop=" alt="" /></div>
  <div class="img-w"><img src="https://images.unsplash.com/photo-1485871800663-71856dc09ec4?dpr=1&auto=format&fit=crop&w=1500&h=2250&q=80&cs=tinysrgb&crop=" alt="" /></div>
  <div class="img-w"><img src="https://images.unsplash.com/photo-1485871882310-4ecdab8a6f94?dpr=1&auto=format&fit=crop&w=1500&h=2250&q=80&cs=tinysrgb&crop=" alt="" /></div>
  <div class="img-w"><img src="https://images.unsplash.com/photo-1485872304698-0537e003288d?dpr=1&auto=format&fit=crop&w=1500&h=1000&q=80&cs=tinysrgb&crop=" alt="" /></div>
  <div class="img-w"><img src="https://images.unsplash.com/photo-1485872325464-50f17b82075a?dpr=1&auto=format&fit=crop&w=1500&h=1000&q=80&cs=tinysrgb&crop=" alt="" /></div>
  <div class="img-w"><img src="https://images.unsplash.com/photo-1470171119584-533105644520?dpr=1&auto=format&fit=crop&w=1500&h=886&q=80&cs=tinysrgb&crop=" alt="" /></div>
  <div class="img-w"><img src="https://images.unsplash.com/photo-1485881787686-9314a2bc8f9b?dpr=1&auto=format&fit=crop&w=1500&h=969&q=80&cs=tinysrgb&crop=" alt="" /></div>
  <div class="img-w"><img src="https://images.unsplash.com/photo-1485889397316-8393dd065127?dpr=1&auto=format&fit=crop&w=1500&h=843&q=80&cs=tinysrgb&crop=" alt="" /></div>

Style the gallery using the following CSS styles:

body {
  padding: 30px 0;
  position: relative;

.gallery {
  width: 600px;
  margin: auto;
  border-radius: 3px;
  overflow: hidden;

.img-c {
  width: 200px;
  height: 200px;
  float: left;
  position: relative;
  overflow: hidden;

.img-w {
  position: absolute;
  width: 100%;
  height: 100%;
  background-size: cover;
  background-position: center;
  cursor: pointer;
  transition: transform ease-in-out 300ms;

.img-w img {
  display: none;

.img-c {
  transition: width ease 400ms, height ease 350ms, left cubic-bezier(0.4, 0, 0.2, 1) 420ms, top cubic-bezier(0.4, 0, 0.2, 1) 420ms;

.img-c:hover .img-w {
  transform: scale(1.08);
  transition: transform cubic-bezier(0.4, 0, 0.2, 1) 450ms;

.img-c.active {
  width: 100% !important;
  height: 100% !important;
  position: absolute;
  z-index: 2;

.img-c.postactive {
  position: absolute;
  z-index: 2;
  pointer-events: none;

.img-c.active.positioned {
  left: 0 !important;
  top: 0 !important;
  transition-delay: 50ms;

Load the jQuery by adding the following CDN link before closing the body tag:

<script src='https://cdnjs.cloudflare.com/ajax/libs/jquery/3.1.1/jquery.min.js'></script>

Finally, add the following jQuery gallery function to activate the zoom hover effect.

$(function() {
  $(".img-w").each(function() {
    $(this).wrap("<div class='img-c'></div>")
    let imgSrc = $(this).find("img").attr("src");
     $(this).css('background-image', 'url(' + imgSrc + ')');
  $(".img-c").click(function() {
    let w = $(this).outerWidth()
    let h = $(this).outerHeight()
    let x = $(this).offset().left
    let y = $(this).offset().top
    let copy = $(this).clone();
    $(".active").css('top', y - 8);
    $(".active").css('left', x - 8);
      setTimeout(function() {
  }, 0)

$(document).on("click", ".img-c.active", function() {
  let copy = $(this)
  copy.removeClass("positioned active").addClass("postactive")
  setTimeout(function() {
  }, 500)

Code Explanation

First, the code waits for the page to load by wrapping the code in $(function() { ... }). Then, for each element with the class “img-w”, the code wraps it in a div with the class “img-c” and sets the background image of the new div to be the same as the source of the image within the “img-w” element.

Next, when an “img-c” element is clicked, the code creates a copy of the element, removes any other elements with the class “active”, resizes and positions the copy of the element, and sets a delay of 500 milliseconds before adding the class “active”. The positioned class is added with a zero-millisecond delay, so it is added immediately after the active class.

Finally, when an “img-c active” element is clicked, the code removes the element after a delay of 500 milliseconds by first removing the “positioned” and “active” classes and adding the “postactive” class. The element is then removed from the DOM with a delay of 500 milliseconds.
