Bootstrap carousel reveal part of next slide

问题

I have a bootstrap carousel that is currently scrolling vertically. Is there a way to show a part of the next slide (say 33%) that will sit at the bottom and would sit above the current slide and ideally slide up when sliding. I've set up a fiddle with what I currently have.

Html:

<div class="container">
  <div class="page-header">
    <h1>Bootstrap Vertical Carousel</h1>
    <p class="lead">Out of the box, Bootstrap only comes with a traditional horizontal  carousel. This Pen has the HTML and CSS to get it to animate vertically with up/down carousel controls.</p>
  </div>
</div>

<div class="bg-info">
  <div class="container">
    <div id="carousel-example-vertical" class="carousel vertical slide">
      <div class="carousel-inner" role="listbox">
        <div class="item active">
          <img src="http://placehold.it/350x150/123456">
        </div>
        <div class="item">
          <p class="ticker-headline">
            <img src="http://placehold.it/350x150/236152">
          </p>
        </div>
        <div class="item">
          <img src="http://placehold.it/350x150/096437">
        </div>
        <div class="item">
          <img src="http://placehold.it/350x150/000000">
        </div>
      </div>

      <!-- Controls -->
      <a class="up carousel-control" href="#carousel-example-vertical" role="button" data-slide="prev">
        <span class="glyphicon glyphicon-chevron-up" aria-hidden="true"></span>
        <span class="sr-only">Previous</span>
      </a>
      <a class="down carousel-control" href="#carousel-example-vertical" role="button" data-slide="next">
        <span class="glyphicon glyphicon-chevron-down" aria-hidden="true"></span>
        <span class="sr-only">Next</span>
      </a>
    </div>
  </div>
</div>

Css:

body {
  margin: 50px 0;

It's not possible without a serious rewrite. Fundamentally, this plugin works by hiding all of the slides:

.carousel-inner>.item {
    position: relative;
    display: none; <- culprit
    -webkit-transition: .6s ease-in-out left;
    -o-transition: .6s ease-in-out left;
    transition: .6s ease-in-out left;
}

However, even if we disable that rule, the animation is still broken. The code displays and repositions one slide at a time.

My recommendation is to look for another plugin that more closely matches your needs.
