【问题描述】：

我的 Carousel 会全屏显示，但我希望它更小，例如在左右两边留出一个边距，这样它就不会占据整个页面。用 CSS 尝试过，但到目前为止没有运气。

<section id="slider">
  <div id="carouselExampleIndicators" class="carousel slide" data-ride="carousel">
    <ol class="carousel-indicators">
      <li data-target="#carouselExampleIndicators" data-slide-to="0" class="active"></li>
      <li data-target="#carouselExampleIndicators" data-slide-to="1"></li>
      <li data-target="#carouselExampleIndicators" data-slide-to="2"></li>
    </ol>
    <div class="carousel-inner">
      <div class="carousel-item active"> <img class="d-block w-100" src="wildfire1.jpg" alt="waldbrband1"> </div>
      <div class="carousel-item"> <img class="d-block w-100" src="wildfire2.jpg" alt="waldbrand2"> </div>
      <div class="carousel-item"> <img class="d-block w-100" src="wildfire3.jpg" alt="waldbrand3"> </div>
    </div>
    <a class="carousel-control-prev" href="#carouselExampleIndicators" 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="#carouselExampleIndicators" role="button" data-slide="next"> <span class="carousel-control-next-icon" aria-hidden="true"></span> <span class="sr-only">Next</span> </a> 
  </div>
</section>

【问题讨论】：

您还必须为 Bootstrap 3 添加 class="img-responsive" 和为 Bootstrap 4 添加 class="img-fluid"

标签： javascript html css twitter-bootstrap carousel

【解决方案1】：

我不确定这是不是最好的方法，但您可以像这样将代码放入容器中：

<div class="MySlider-container">
<section id="slider">
  <div id="carouselExampleIndicators" class="carousel slide" data-ride="carousel">
    <ol class="carousel-indicators">
      <li data-target="#carouselExampleIndicators" data-slide-to="0" class="active"></li>
      <li data-target="#carouselExampleIndicators" data-slide-to="1"></li>
      <li data-target="#carouselExampleIndicators" data-slide-to="2"></li>
    </ol>
    <div class="carousel-inner">
      <div class="carousel-item active"> <img class="d-block w-100" src="wildfire1.jpg" alt="waldbrband1"> </div>
      <div class="carousel-item"> <img class="d-block w-100" src="wildfire2.jpg" alt="waldbrand2"> </div>
      <div class="carousel-item"> <img class="d-block w-100" src="wildfire3.jpg" alt="waldbrand3"> </div>
    </div>
    <a class="carousel-control-prev" href="#carouselExampleIndicators" 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="#carouselExampleIndicators"
      role="button" data-slide="next"> <span class="carousel-control-next-icon" aria-hidden="true"></span> <span class="sr-only">Next</span> </a> 
  </div>
</section>
</div>

你的 css 代码看起来像这样：

.MySlider-container {
  margin-left: 5rem;
  margin-right: 5rem;
}
