Question

引导旋转木马是否可以伸缩以显示滑块中的下一个和上一个图像？

    <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>

我的旋转木马目前看起来像这样，我如何将上一张和下一张图片添加到当前活动的幻灯片中？

Answer 1

可以使用Bootstrap，但需要一些自定义......

在Bootply上查看此示例：http://bootply.com/94444

您必须使用CSS和jQuery自定义幻灯片的位置。

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

另一个变体只显示下一张和上一张幻灯片的一部分。这可以通过在carousel-inner ..

的左侧和右侧放置绝对位置叠加来完成

.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;
}
