A jQuery/HTML5/CSS3 based modal script to create simple, responsive, animated, and reuseable modal popups on your website/application.

How to use it:

1. Create a modal box.

<div id="popup" class="modal-box">  
  <header>
    <a href="#" class="js-modal-close close">×</a>
    <h3>Modal Title</h3>
  </header>
  <div class="modal-body">
    <p>Modal Body</p>
  </div>
  <footer>
    <a href="#" class="js-modal-close">Close Button</a>
  </footer>
</div>

2. Create a link to open the modal box. Use Html5 data-modal-id attribute to specify the associated modal DIV.

<a class="js-open-modal" href="#" data-modal-id="popup"> Click me </a>

3. The CSS to style the modal box.

.modal-box {
  display: none;
  position: absolute;
  z-index: 1000;
  width: 98%;
  background: white;
  border-bottom: 1px solid #aaa;
  border-radius: 4px;
  box-shadow: 0 3px 9px rgba(0, 0, 0, 0.5);
  border: 1px solid rgba(0, 0, 0, 0.1);
  background-clip: padding-box;
}

.modal-box header,
.modal-box .modal-header {
  padding: 1.25em 1.5em;
  border-bottom: 1px solid #ddd;
}

.modal-box header h3,
.modal-box header h4,
.modal-box .modal-header h3,
.modal-box .modal-header h4 { margin: 0; }

.modal-box .modal-body { padding: 2em 1.5em; }

.modal-box footer,
.modal-box .modal-footer {
  padding: 1em;
  border-top: 1px solid #ddd;
  background: rgba(0, 0, 0, 0.02);
  text-align: right;
}

.modal-overlay {
  opacity: 0;
  filter: alpha(opacity=0);
  position: absolute;
  top: 0;
  left: 0;
  z-index: 900;
  width: 100%;
  height: 100%;
  background: rgba(0, 0, 0, 0.3) !important;
}

a.close {
  line-height: 1;
  font-size: 1.5em;
  position: absolute;
  top: 5%;
  right: 2%;
  text-decoration: none;
  color: #bbb;
}

a.close:hover {
  color: #222;
  -webkit-transition: color 1s ease;
  -moz-transition: color 1s ease;
  transition: color 1s ease;
}

4. Make the modal box responsive using CSS3 media queries.

@media (min-width: 32em) {
  .modal-box { width: 70%; }
}

5. The jQuery script to enable the modal box. Place the following JavaScript library after you have jQuery installed.

$(function(){

var appendthis =  ("<div class='modal-overlay js-modal-close'></div>");

  $('a[data-modal-id]').click(function(e) {
    e.preventDefault();
    $("body").append(appendthis);
    $(".modal-overlay").fadeTo(500, 0.7);
    //$(".js-modalbox").fadeIn(500);
    var modalBox = $(this).attr('data-modal-id');
    $('#'+modalBox).fadeIn($(this).data());
  });  
  
  
$(".js-modal-close, .modal-overlay").click(function() {
  $(".modal-box, .modal-overlay").fadeOut(500, function() {
    $(".modal-overlay").remove();
  });
});
 
$(window).resize(function() {
  $(".modal-box").css({
    top: ($(window).height() - $(".modal-box").outerHeight()) / 2,
    left: ($(window).width() - $(".modal-box").outerWidth()) / 2
  });
});
 
$(window).resize();
 
});
