Question

我有一个简单的bootstrap 4轮播，我希望轮播标题出现在顶部而不是下面的底部。

更新：此处是带有完整代码的JSFIDLE

这是我到目前为止尝试过的

HTML

<div class="modal fade" id="myModal">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-header">
                <div class="pull-left">My Gallery Title</div>
                <button type="button" class="close" data-dismiss="modal" aria-label="Close">
                    <span aria-hidden="true">&times;</span>
                  </button>
            </div>
            <div class="modal-body">
                <div id="demo" class="carousel slide" data-ride="carousel">

                    <!-- Indicators -->
                    <ul class="carousel-indicators">
                      <li data-target="#demo" data-slide-to="0" class="active"></li>
                      <li data-target="#demo" data-slide-to="1"></li>
                      <li data-target="#demo" data-slide-to="2"></li>
                    </ul>

                    <!-- The slideshow -->
                    <div class="carousel-inner">
                      <div class="carousel-item active">
                            <div class="carousel-caption">
                                    <h3>Heading 1</h3>
                                    </div>
                        <img src="https://placeimg.com/600/400/nature/1" alt="Los Angeles">
                      </div>
                      <div class="carousel-item">
                            <div class="carousel-caption">
                                    <h3>Heading 2</h3>
                                    </div>
                        <img src="https://placeimg.com/600/400/nature/2" alt="Chicago">
                      </div>
                      <div class="carousel-item">
                            <div class="carousel-caption">
                                    <h3>Heading 3</h3>
                                    </div>
                        <img src="https://placeimg.com/600/400/nature/3" alt="New York">
                      </div>
                    </div>

                    <!-- Left and right controls -->
                    <a class="carousel-control-prev" href="#demo" data-slide="prev">
                      <span class="carousel-control-prev-icon"></span>
                    </a>
                    <a class="carousel-control-next" href="#demo" data-slide="next">
                      <span class="carousel-control-next-icon"></span>
                    </a>
                  </div>

            </div>
            <div class="modal-footer">
                <button class="btn-sm close" type="button" data-dismiss="modal">Close</button>
                <!--end modal-footer-->
            </div>
            <!--end modal-content-->
        </div>
        <!--end modal-dialoge-->
    </div>
    <!--end myModal-->>
</div>

CSS

.carousel-caption {
    position: absolute;
    right: 15%;
    top: -42px;
    left: 15%;
    z-index: 999999999;
    padding-top: 20px;
    padding-bottom: 20px;
    color: #fff;
    text-align: center;
}

不幸的是，有了这种解决方案，我的轮播字幕消失了。

我需要做什么才能得到我想要的东西？

Answer 1

将top的值更改为0。轮播标题将移动到轮播顶部，与轮播指示器完全相反。尝试使用检查元素并检查关注元素的位置。

Answer 2

更改css中的.carousel-caption

.carousel-item .carousel-caption {
  position: static;
  padding-top: 20px;
  padding-bottom: 20px;
  text-align: center;
}

Answer 3

在div中使用与类“ .carousel-item”相对的属性

.carousel-item{
  position:relative;
}
.carousel-caption {
  position: absolute;
  top: 0;
  left: 0;
  width:100%;
  text-align:center;
  z-index: 999999999;
  padding-top: 5px;
  color: #fff;
}
