reduce bottom image height我是学生，正在尝试使用 Bootstrap Carousel插件，并且正在使用w3school轮播示例[https://www.w3schools.com/bootstrap/tryit.asp?filename=trybs_carousel&stacked=h]，因此我需要增加底部高度的Carousel Image按钮太低了，谁能帮我。我在下面附了一张照片

这是我尝试过的代码

  <section id="intro" class="clearfix" style="
      padding: 80px 0 60px 0;
      padding-top: 80px;
      padding-right: 0px;
      padding-bottom: 60px;
      padding-left: 0px;
  ">
          <div class="container d-flex h-100">

        <div id="myCarousel" class="carousel slide" data-ride="carousel">

          <ol class="carousel-indicators">
            <li data-target="#myCarousel" data-slide-to="0" class="active"></li>
            <li data-target="#myCarousel" data-slide-to="1"></li>
            <li data-target="#myCarousel" data-slide-to="2"></li>
          </ol>


          <div class="carousel-inner">
            <div class="item active">
              <img src="img/dog2.jpg" alt="Los Angeles"  class="img-fluid" alt="Responsive image">
            </div>

            <div class="item">
              <img src="img/duffy-brook-350228-2000x1333.jpg" alt="Chicago"  class="img-fluid" alt="Responsive image">
            </div>

            <div class="item">
              <img src="img/dog2.jpg" alt="New york"  class="img-fluid" alt="Responsive image">
            </div>
          </div>


          <a class="left carousel-control" href="#myCarousel" data-slide="prev">
            <span class="glyphicon glyphicon-chevron-left"></span>
            <span class="sr-only">Previous</span>
          </a>
          <a class="right carousel-control" href="#myCarousel" data-slide="next">
            <span class="glyphicon glyphicon-chevron-right"></span>
            <span class="sr-only">Next</span>
          </a>
        </div>
      </div>
</section>

您的ol有bottom: 10px;

更改bottom属性的值以更改垂直位置

添加以下CSS

CSS 

ol.carousel-indicators {
  bottom: 0;
}

HTML 

<ol style="bottom: 0;" class="carousel-indicators">

请参见示例here

您需要将top:50%添加到carousel-indicators 

.carousel-indicators {
  top: 50%;
}

如果要减小carousel的高度，可以根据需要指定height 

.carousel-inner {
  height: 50vh!important
}

 .carousel-inner .item.active,
.carousel-inner .item {
  height: 50vh!important;
}

.item img {
  object-fit: cover;
  width: 100%!important;
  height: 100% !important;
}
