title: finding element in the active slide of Bootstrap carousel
body: <p>I'm trying to do something to a div that is inside a Bootstrap 3 carousel. How do I find that div, though?</p>
  
  <pre><code> $('.carousel').on('slid.bs.carousel', function () {
      var carouselData = $(this).data('bs.carousel');
                var currentIndex = carouselData.getItemIndex(carouselData.$element.find('.item.active'));
  
      //now I know the current item, but how do I change the .description div
      //inside that item?
  
  
      });
  </code></pre>
