Auto Height

Setup

Add height to div="owl-wrapper-outer" so you can use diffrent heights on each slide. Use it only for one item per page setting. Don't use it on large content websites.

$(document).ready(function() {

  $("#owl-demo").owlCarousel({
    autoPlay : 3000,
    stopOnHover : true,
    navigation:true,
    paginationSpeed : 1000,
    goToFirstSpeed : 2000,
    singleItem : true,
    autoHeight : true,
    transitionStyle:"fade"
  });

});
