幅100%で前後の要素はチラリと表示されるスライドショーです。

carouFredSel を使っているので、先にjqueryとjquery.carouFredSel-6.2.1.jsを読み込みます。

JSを読み込みます

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script src="../js/jquery.carouFredSel-6.2.1.js"></script>

JavaScript

<script type="text/javascript" language="javascript">
jQuery(document).ready(function($){
  $('#carousel').carouFredSel({
	width: '100%',
  auto:4000,
	prev : "#slide_prev",
	next : "#slide_next",
  items: {
    visible: 3,
    start: -1
  },
  scroll: {
    items  : 1,
		onBefore: function( data ) {
		  data.items.old.eq(1).removeClass('selected');
			data.items.visible.eq(1).addClass('selected');
	},
  easing : "swing",
  duration  : 800 
  },
  visible:{
	  min:3,
		max:3
	},
  pagination: {
    container: '#pager',
    deviation: 1
  }
  });
});
