Bootstrap Carousel showing next and previous image

问题:

Is the bootstrap carousel extendible to show the next and previous images in the slider?

    <div id="carousel-example-generic" class="carousel slide" data-ride="carousel" data-interval="false">
      <!-- Indicators -->
      <ol class="carousel-indicators">
        <li data-target="#carousel-example-generic" data-slide-to="0" class="active"></li>
        <li data-target="#carousel-example-generic" data-slide-to="1"></li>
      </ol>

      <!-- Wrapper for slides -->
      <div class="carousel-inner">
        <div class="item active">
          <img src="img/bike.png" alt="...">
          <div class="carousel-caption">
            ...
          </div>
        </div>
        <div class="item">
          <img src="img/bike2.png" alt="...">
          <div class="carousel-caption">
            ...
          </div>
        </div>
      </div>

      <!-- Controls -->
      <a class="left carousel-control" href="#carousel-example-generic" data-slide="prev">
        <span class="glyphicon glyphicon-chevron-left"></span>
      </a>
      <a class="right carousel-control" href="#carousel-example-generic" data-slide="next">
        <span class="glyphicon glyphicon-chevron-right"></span>
      </a>
    </div> 

My carousel looks like this at the moment, how can i add in the previous and next images to the currently active slide?

It is possible with Bootstrap, but requires some customizations...

See this example on Bootply: http://bootply.com/94444

You have to customize the position of the slides using CSS and jQuery..

.carousel-inner .active.left { left: -33%; }
.carousel-inner .next        { left:  33%; }
.carousel-inner .prev        { left: -33%; }

Another variation is only reveal a portion of the next and previous slides. This can be done by placing an absolute position overlay over the left and right side of the carousel-inner..

.carousel-inner:before {
    position:absolute;
    top:0;
    bottom: 0;
    right: 82%;
    left: 0;
    content:"";
    display:block;
    background-color: #fff;
    z-index: 2;
}
.carousel-inner:after {
    position:absolute;
    top:0;
    bottom:0;
    right: 0;
    left: 82%;
    content:"";
    display:block;
    background-color:#fff;
    z-index: 2;
}

I experienced that Bootstrap 3.3.5 is not supports the given solution unfortunately, there I made a completely new Bootstrap 3 carousel extension to reach the goal. It can be found at https://github.com/assarte/visor-carousel

Hope this could be helpful.
