A simple, effective and responsive jQuery accordion plugin for expanding/collapsing content panels with smooth slide animations based on CSS3 transition.

How to use it:

1. Include the jquery.expandAccordion.css for basic accordion styles/animations.

<link rel="stylesheet" href="css/jquery.expandAccordion.css">

2. Create a set of Html elements for the accordion.

<div class="expand_accordion" id="expand_accordion">
  <div class="main">
    <div class="item">
      <div class="item_header">
        <div class="inner"> <span>Header 1</span> </div>
      </div>
      <div class="item_content">
        <div class="inner"> Content 1 </div>
      </div>
    </div>
    <div class="item">
      <div class="item_header">
        <div class="inner"> <span>Header2</span> </div>
      </div>
      <div class="item_content">
        <div class="inner"> Content 2 </div>
      </div>
    </div>
    <div class="item">
      <div class="item_header">
        <div class="inner"> <span>Header 3</span> </div>
      </div>
      <div class="item_content">
        <div class="inner"> Content 3 </div>
      </div>
    </div>
  </div>
</div>

3. Include the latest jQuery library and the jQuery expandAccordion plugin at the bottom of the document so the pages load faster.

<script src="//code.jquery.com/jquery-1.11.1.min.js"></script>
<script src="js/jquery.expandAccordion.js"></script>

4. Call the plugin on the parent container to make the set of elements act like a vertical accordion.

$("#expand_accordion").expandAccordion({
  // OPTIONS
});

5. Add the custom CSS to style the accordion whatever you like.

.header,
.footer { background: #F7F7F7; }

.header > .inner > h1 {
  display: block;
  position: absolute;
  bottom: 22px;
  left: 22px;
  line-height: 44px;
  font-size: 44px;
  font-weight: 300;
}

.footer > .inner {
  display: block;
  width: 100%;
  height: 100%;
}

.footer > .inner > a {
  display: inline-block;
  position: absolute;

  background: #D7D7D7;
