Bootstrap v4：純文字輪播僅在滑動完成時居中顯示文字（否則貼在頂部）

Question

知道為什么該純文本輪播（Bootstrap v4）會將我的輪播項目文本粘貼在頂部，然后將其居中對齊，而不是直接正確地對齊項目的文本嗎？

<div id="myTextOnlyCarousel" class="carousel slide mt-5" data-ride="carousel">
  <ol class="carousel-indicators">
    <li data-target="#myTextOnlyCarousel" data-slide-to="0" class="active"></li>
    <li data-target="#myTextOnlyCarousel" data-slide-to="1"></li>
    <li data-target="#myTextOnlyCarousel" data-slide-to="2"></li>
  </ol>
  <div class="carousel-inner bg-dark text-light rounded text-center d-flex h-100 align-items-center justify-content-center" style="min-height: 300px;">
    <div class="carousel-item active">
      <h1>This is AWESOME!</h1>
    </div>
    <div class="carousel-item">
      <h1>This is freaking AMAZING!</h1>
    </div>
    <div class="carousel-item">
      <h1>YEAHHH</h1>
    </div>
  </div>
  <a class="carousel-control-prev" href="#myTextOnlyCarousel" role="button" data-slide="prev">
    <span class="carousel-control-prev-icon" aria-hidden="true"></span>
    <span class="sr-only">Previous</span>
  </a>
  <a class="carousel-control-next" href="#myTextOnlyCarousel" role="button" data-slide="next">
    <span class="carousel-control-next-icon" aria-hidden="true"></span>
    <span class="sr-only">Next</span>
  </a>
</div>

好的，這是因為輪播項目類上的活動類才使文本在動畫中滑動。 因此，將其更改為展示廣告塊，然后添加從輪播中刪除彎曲部分。

 .carousel-item .text{ display: flex; height: 100%!important; min-height: 300px; align-items: center; justify-content: center; } .carousel-item.active, .carousel-item-next, .carousel-item-prev{ display:block; } 

 <div id="myTextOnlyCarousel" class="carousel slide mt-5" data-ride="carousel"> <ol class="carousel-indicators"> <li data-target="#myTextOnlyCarousel" data-slide-to="0" class="active"></li> <li data-target="#myTextOnlyCarousel" data-slide-to="1"></li> <li data-target="#myTextOnlyCarousel" data-slide-to="2"></li> </ol> <div class="carousel-inner bg-dark text-light rounded text-center h-100 " style="min-height: 300px;background: red;"> <div class="carousel-item active"> <div class="text"> <h1>This is AWESOME!</h1> </div> </div> <div class="carousel-item"> <div class="text"> <h1>This is freaking AMAZING!</h1> </div> </div> <div class="carousel-item"> <div class="text"> <h1>YEAHHH</h1> </div> </div> </div> <a class="carousel-control-prev" href="#myTextOnlyCarousel" role="button" data-slide="prev"> <span class="carousel-control-prev-icon" aria-hidden="true"></span> <span class="sr-only">Previous</span> </a> <a class="carousel-control-next" href="#myTextOnlyCarousel" role="button" data-slide="next"> <span class="carousel-control-next-icon" aria-hidden="true"></span> <span class="sr-only">Next</span> </a> </div>

這是我的解決方案JSFiddle

我用wrapper您的h1 。

我必須給出最小高度，因為沒有它，這些項目將停留在頂部。

.wrapper {
  min-height:300px;
  display: flex;
  align-items: center;
  justify-content: center;
}

並刪除了一些應用於.carousel-inner div的flex類
