Google Style Draggable Modal Window with Pure JavaScript

Description:

A lightweight JavaScript library to create a responsive, drag’n’drop modal window with support keyboard shortcuts. Inspired by Google Modal and based on Draggabilly PACKAGED library.

How to use it:

Load the draggabilly.pkgd.js and modal.js in the html page.

<script src="js/draggabilly.pkgd.js"></script>
<script src="js/modal.js"></script>

Create a modal window following the markup structure like so:

<div class="modal">
  <header class="modal-header">
    <h1 class="modal-header-title left">Title of Modal</h1>
    <button class="modal-header-btn right modal-close" title="Close Modal">OK</button>
  </header>
  <div class="modal-body">
    <section class="modal-content">
      Modal Content Goes Here
    </section>
  </div>
</div>

Create a button to launch the modal window.

<button class="modal-header-btn modal-trigger btn-fixed">Open Modal</button>

The basic CSS styles for the modal window.
