Minimalist Image Lightbox With Smooth CSS Animations

A minimal image viewer jQuery script that enlarges and displays images in a fullscreen lightbox, with custom CSS3 powered open/close animations.

How to use it:

1. Create the HTML for the image viewer (lightbox).

<div id="image-viewer">
  <span class="close">&times;</span>
  <img class="modal-content" id="full-image">
</div>

2. The main JavaScript (jQuery script) to trigger the image lightbox when clicking on the image within your page.

<div class="images">
  <img src="1.jpg" alt="My Image" width="400" height="300" />
</div>

<script src="/path/to/cdn/jquery.slim.min.js"></script>

$(".images img").click(function(){
  $("#full-image").attr("src", $(this).attr("src"));
  $('#image-viewer').show();
});

$("#image-viewer .close").click(function(){
  $('#image-viewer').hide();
});

3. Style the image uses as the lightbox trigger.

img {
  border-radius: 5px;
  cursor: pointer;
  transition: 0.3s;
}

img:hover {
  opacity: 0.7;
}

4. The main CSS styles & animations for the image lightbox.

#image-viewer {
  display: none;
  position: fixed;
  z-index: 1;
  padding-top: 100px;
  left: 0;
  top: 0;
  width: 100%;
  height: 100%;
  overflow: auto;
  background-color: rgb(0,0,0);
  background-color: rgba(0,0,0,0.9);
}

.modal-content {
  margin: auto;
  display: block;
  width: 80%;
  max-width: 700px;
}

.modal-content { 
  animation-name: zoom;
  animation-duration: 0.6s;
}

@keyframes zoom {
  from {transform:scale(0)} 
  to {transform:scale(1)}
}

#image-viewer .close {
  position: absolute;
  top: 15px;
  right: 35px;
  color: #f1f1f1;
  font-size: 40px;
  font-weight: bold;
  transition: 0.3s;
}

#image-viewer .close:hover,
#image-viewer .close:focus {
  color: #bbb;
  text-decoration: none;
  cursor: pointer;
}

@media only screen and (max-width: 700px){
  .modal-content {
      width: 100%;
  }
}
