Whenever an image is clicked, a lightbox appears. Currently, the image overlay is positioned at the top of the screen, but ideally, it should be centered on the user's screen.
See the code snippet below:
// The following script creates a lightbox
(function() {
var $lightbox = $("<div class='lightbox'></div>");
var $img = $("<img>");
var $caption = $("<p class='caption'></p>");
// Insert image and caption into the lightbox
$lightbox
.append($img)
.append($caption);
// Add lighbox to document
$('body').append($lightbox);
$('.lightbox-gallery img').click(function(e) {
e.preventDefault();
// Extract image link and description
var src = $(this).attr("src");
var cap = $(this).attr("alt");
var txt = $(this).parent().find('.js-text').text()
// Populate the lightbox with data
$img.attr('src', src);
$caption.text(txt);
// Show lightbox
$lightbox.fadeIn('fast');
$lightbox.click(function() {
$lightbox.fadeOut('fast');
});
});
}());body{
