Question

我看到了带有bootstrap 3 here缩略图的旋转木马演示。

我正在尝试为bootstrap v4实现相同的功能，但是无法弄清楚如何修复一些UI细节，例如左/右阴影来自整个高度，包括缩略图。 Here是v4的小提琴。

以下是HTML代码：

<div id='carousel-custom' class='carousel slide' data-ride='carousel'>
        <!-- Wrapper for slides -->
        <div class='carousel-inner'>
            <div class='carousel-item active'>
                <img src='http://placehold.it/400x200&text=slide1' alt='' />
            </div>
            <div class='carousel-item'>
                <img src='http://placehold.it/400x200&text=slide2' alt='' />
            </div>
            <div class='carousel-item'>
                <img src='http://placehold.it/400x200&text=slide3' alt='' />
            </div>
        </div>

        <!-- Controls -->
        <a class='left carousel-control' href='#carousel-custom' data-slide='prev'>
            <span class='glyphicon glyphicon-chevron-left'></span>
        </a>
        <a class='right carousel-control' href='#carousel-custom' data-slide='next'>
            <span class='glyphicon glyphicon-chevron-right'></span>
        </a>


    <!-- Indicators -->
    <ol class='carousel-indicators'>
        <li data-target='#carousel-custom' data-slide-to='0' class='active'><img src='http://placehold.it/100x50&text=slide1' alt='' /></li>
        <li data-target='#carousel-custom' data-slide-to='1'><img src='http://placehold.it/100x50&text=slide2' alt='' /></li>
        <li data-target='#carousel-custom' data-slide-to='2'><img src='http://placehold.it/100x50&text=slide3' alt='' /></li>

    </ol>
</div>

CSS更改：

#carousel-example-generic {
    margin: 20px auto;
    width: 400px;
}

#carousel-custom {
    margin: 20px auto;
    width: 400px;
}
#carousel-custom .carousel-indicators {
    margin: 10px 0 0;
    overflow: auto;
    position: static;
    text-align: left;
    white-space: nowrap;
    width: 100%;
}
#carousel-custom .carousel-indicators li {
    background-color: transparent;
    -webkit-border-radius: 0;
    border-radius: 0;
    display: inline-block;
    height: auto;
    margin: 0 !important;
    width: auto;
}
#carousel-custom .carousel-indicators li img {
    display: block;
    opacity: 0.5;
}
#carousel-custom .carousel-indicators li.active img {
    opacity: 1;
}
#carousel-custom .carousel-indicators li:hover img {
    opacity: 0.75;
}

对于Bootstrap 4，可能更容易使用list-inline作为滑块缩略图，而且您不需要额外的CSS。

    <div class="col-lg-6 offset-lg-3" id="slider">
            <div id="myCarousel" class="carousel slide">
                <div class="carousel-inner">
                    <div class="active item carousel-item" data-slide-number="0">
                        <img src="http://placehold.it/1200x480&amp;text=one" class="img-fluid">
                    </div>
                    <div class="item carousel-item" data-slide-number="1">

如果您将控件移动到.carousel-inner元素中，则不会缩小缩略图：

<div class='carousel-inner'>
    <div class='carousel-item active'>
        <img src='http://placehold.it/400x200&text=slide1' alt='' />
    </div>
    <div class='carousel-item'>
        <img src='http://placehold.it/400x200&text=slide2' alt='' />
    </div>
    <div class='carousel-item'>
        <img src='http://placehold.it/400x200&text=slide3' alt='' />
    </div>

    <div class='carousel-item'>
        <img src='http://placehold.it/400x200&text=slide4' alt='' />
    </div>
    <div class='carousel-item'>
        <img src='http://placehold.it/400x200&text=slide5' alt='' />
    </div>
    <div class='carousel-item'>
        <img src='http://placehold.it/400x200&text=slide6' alt='' />
    </div>

    <div class='carousel-item'>
        <img src='http://placehold.it/400x200&text=slide7' alt='' />
    </div>
    <div class='carousel-item'>
        <img src='http://placehold.it/400x200&text=slide8' alt='' />
    </div>
    <div class='carousel-item'>
        <img src='http://placehold.it/400x200&text=slide9' alt='' />
    </div>

    <!-- Controls -->
    <a class='left carousel-control' href='#carousel-custom' data-slide='prev'>
      <span class='glyphicon glyphicon-chevron-left'></span>
    </a>
    <a class='right carousel-control' href='#carousel-custom' data-slide='next'>
      <span class='glyphicon glyphicon-chevron-right'></span>
    </a>

</div>
