轮播指标引导程序 4 不采用 css 样式

Question

我正在尝试为 bootstrap 4 轮播指示器设置样式，如下图所示，但我无法这样做。

.carousel-indicators {
    width: auto;
    padding: 8px 18px;
    background-color: rgba(96,107,114,.8);
    border-radius: 18px;
    line-height: 0;
   
}


.carousel-indicators li {
  border-radius: 50% !important;
  width: 12px;
  height: 12px;
}

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" integrity="sha384-Gn5384xqQ1aoWXA+058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm" crossorigin="anonymous">


<ul 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>
        </ul>
<script src="https://code.jquery.com/jquery-3.2.1.slim.min.js" integrity="sha384-KJ3o2DKtIkvYIK3UENzmM7KCkRr/rE9/Qpg6aAZGJwFDMVNA/GpGFF93hXpG5KkN" crossorigin="anonymous"></script>

在我的情况下，背景的宽度更大。我尝试过定位和翻译，但无法这样做。我无法像上图那样实现。 谁能帮我解决这个问题。

Answer 1

您可以使用!important 使其工作。这是必需的，因为它需要覆盖引导程序的样式。

强烈建议不要使用此方法。我建议您使用 Bootstrap Sass 来生成您需要的 css。您可以在 _variables 文件中定义样式的变量。

好的，我在回答之前没有阅读完整的问题。您还需要覆盖一些默认的引导类以获得类似的指标。

.carousel-indicators {
  /* required to override bootstrap */
  right: unset !important;
  left: unset !important;
  padding-left: 18px !important;
  margin-right: unset !important;
  margin-left: unset !important;
  /* your css styles */
  width: auto;
  padding: 8px 18px;
  background-color: rgba(96, 107, 114, .8);
  border-radius: 18px;
  line-height: 0;
}

.carousel-indicators li {
  border-radius: 50% !important;
  width: 12px !important;
  height: 12px !important;
}
