html - Bootstrap Carousel：未显示指标，动画不适用于所有幻灯片，更改幻灯片的背景

问题描述

我想在 BS carousel 图表上的代码中显示指标（h3/p 标签）。看起来它不起作用，躲在图表后面。我们如何让它显示？

以下是我需要解决的问题。

  1. 显示指标（h3，p 标签）。
  2. 动画不适用于所有幻灯片，仅适用于活动幻灯片。
  3. 删除幻灯片中的黑色显示并保留白色背景。

下面是我尝试过的指标标签。

<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>

指示器应显示提及的位置，动画应适用于所有幻灯片并删除/更改默认幻灯片颜色。请检查和帮助。

解决方案

指标在其位置可用。但由于white指标的原因，它没有显示。

尝试应用以下 CSS。

<style>
  .carousel-indicators li {
    background-color: #ccc !important;
  }
  .carousel-indicators .active {
    background-color: #000 !important;
  }
</style>
