Dynamic jQuery Gallery Lightbox Plugin - Simple Gallery

The jQuery Simple Gallery retrieves the image json data from imageData.json and presents the images in a responsive, navigatable lightbox popup when clicked.

How to use it:

1. The plugin requires Bootstrap's stylesheet to style the thumbnail gallery.

<link href="bootstrap.min.css" rel="stylesheet">

2. Create the HTML for the gallery lightbox.

<div class="overlay">
  <div class="content">
    <a href="#" class="closebtn">&times;</a>
    <a class="navigationControls prev">&#10094;</a>
    <a class="navigationControls next">&#10095;</a>
    <img src="" class="img-responsive bigImage"/>
    <div class="imageTitle"></div>
  </div>
</div>

3. Create an empty container to place the thumbnail images.

<div class="container"> 
  <ul class="row galleryContainer">
  </ul>
</div>

4. Load jQuery library and the main JavaScript file 'myscript.js' in the document.

<script src="//code.jquery.com/jquer.min.js"></script>
<script src="js/myscript.js"></script>

5. Override the default image data in the 'imageData.json':

{
  "images": [
    {
      "name": "Image one",
      "imgSource": "1.jpg"
    },
    {
      "name": "Image two",
      "imgSource": "2.jpg"
    },
    {
      "name": "Image three",
      "imgSource": "3.jpg"
    },
    ...
  ]
}

6. The required CSS styles for the gallery lightbox:

ul li {
  list-style: none;
  margin-bottom: 25px;
}

ul li img {
  cursor: pointer;
  border: 3px solid #fff;
  opacity: 0.6;
  transition: opacity 0.5s;
  border-radius: 4px;
}

ul li img:hover { opacity: 1; }

.overlay {
  height: 100%;
  width: 100%;
  position: fixed;
  z-index: 1;
  left: 0;
  top: 0;
  background-color: rgba(0,0,0, 0.6);
  display: none;
}

.overlay .closebtn {
  position: absolute;
  z-index: 3;
  top: -20px;
  right: -30px;
  font-size: 40px;
  color: #f1f1f1;
  text-decoration: none;
}

.prev, .next {
  outline: none;
  text-decoration: none;
  cursor: pointer;
  position: absolute;
  z-index: 3;
  top: 50%;
  width: auto;
  padding: 16px;
  margin-top: -50px;
  color: white;
  font-weight: bold;
  font-size: 20px;
  transition: 0.6s ease;
  border-radius: 0 3px 3px 0;
  user-select: none;
  -webkit-user-select: none;
}

.next {
  right: 0;
  border-radius: 3px 0 0 3px;
}

.prev:hover, .next:hover { background-color: rgba(0, 0, 0, 0.8); }

.bigImage {
  height: 100%;
  width: 100%;
  position: relative;
  border: 3px solid #fff;
}

.content {
  top: 20px;
  position: relative;
  background-color: #fefefe;
  margin: auto;
  padding: 0;
  width: 65%;
  max-width: 1200px;
}

.imageTitle {
  text-align: center;
  padding: 2px;
  height: 25px;
  position: relative;
  background-color: rgba(0,0,0,0.8);
  color: #fff;
  font-size: 15px;
}
