A minimalist jQuery/HTML5/CSS based accordion which allows you to show/hide panels of content with CSS3 powered animations.

How to use it:

1. Build the Html structure for the accordion.

<div id="demo" class="accordion">

  <artical class="ac-panel">
    <header class="ac-header">Header 1</header>
    <section class="ac-content">
      <h3>Title 1</h3>
      <p>Content 1</p>
    </section>
  </artical>

  <artical class="ac-panel">
    <header class="ac-header">Header 2</header>
    <section class="ac-content">
      <h3>Title 2</h3>
      <p>Content 2</p>
    </section>
  </artical>

  <artical class="ac-panel">
    <header class="ac-header">Header 3</header>
    <section class="ac-content">
      <h3>Title 3</h3>
      <p>Content 3</p>
    </section>
  </artical>
  
</div>

2. The core CSS/CSS3 style rules for the accordion.

* {
  -webkit-box-sizing: border-box;
  -moz-box-sizing: border-box;
  box-sizing: border-box;
}

.accordion { }

.ac-panel { display: block; }

.ac-panel.open .ac-content { }

.ac-header {
  display: block;
  cursor: pointer;
}

.ac-content {
  height: 0;
  padding: 0 20px;
  display: block;
  overflow: hidden;
  -webkit-transition: all .3s linear;
  -moz-transition: all .3s linear;
  -o-transition: all .3s linear;
  transition: all .3s linear;
}
