How to use it:

Include the necessary Prefix-free CSS library in the head section of the web page. Prefix-free lets you use only unprefixed CSS properties e.g. transform and transition everywhere.

<script src="prefixfree.min.js"></script>

Create a tabs interface using Html unordered list as follows.

<body class="ready">
<ul class="tabs">
  <li>
    <div class="fold">
      <h3> Title 1 </h3>
      <p> Description 1 </p>
    </div>
    <a href="#" class="more">More</a> </li>
  <li>
    <div class="fold">
      <h3> Title 2 </h3>
      <p> Description 2 </p>
    </div>
    <a href="#" class="more">More</a> </li>
  <li>
    <div class="fold">
      <h3> Title 3 </h3>
      <p> Description 3 </p>
    </div>
    <a href="#" class="more">More</a> </li>
</ul>
