Just another JavaScript library for creating modal popups that are fully controllable via HTML5 data attributes.

How to use it:

Create the modal window with the following HTML data attributes:

  • data-modal-dismiss: open/close the modal
  • data-modal-contain-tabs=”false”: enable/disable tab between input fields
  • data-modal-disable-scroll=”false”: enable/disable page scroll
  • data-modal-animation-duration=”300″: animation duration
  • data-modal-autofocus: auto focus when the modal opens
<div class="modal-container" 
  <div class="modal">
    <header class="modal-header">
      <h2>Modal Title</h2>
      <button class="modal-close" data-modal-dismiss></button>
    <div class="modal-content">
      <p> Modal Content</p>
        <input type="text" placeholder="Text input" data-modal-autofocus>
        <input type="text" placeholder="Text input" data-modal-autofocus>

Create a button to launch the modal window.

<button data-modal-open="modal-demo">Open</button>

Load the main JavaScript file modal.js to active the modal window.

<script src="dist/modal.min.js"></script>

Free feel to customize the modal window with your own CSS styles.
