【问题描述】：

我有一个工作轮播，但我希望调整整个东西的大小。我可以调整图像的大小，但下一个和上一个按钮以及图像指示器不会改变，我不知道如何更改这些以匹配图像的大小。

<div id="homeCarousel" class="carousel slide" data-ride="carousel">
  <ol class="carousel-indicators">
    <li data-target="#homeCarousel" data-slide-to="0" class="active"></li>
    <li data-target="#homeCarousel" data-slide-to="1"></li>
    <li data-target="#homeCarousel" data-slide-to="2"></li>
  </ol>
  <div class="carousel-inner">
    <div class="carousel-item active">
      <img class="d-block w-100" src="images/Makita.png" alt="First slide">
    </div>
    <div class="carousel-item">
      <img class="d-block w-100" src="images/Metabo.png" alt="Second slide">
    </div>
    <div class="carousel-item">
      <img class="d-block w-100" src="images/Bosch.png" alt="Third slide">
    </div>
  </div>
  <a class="carousel-control-prev" href="#homeCarousel" 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="#homeCarousel" role="button" data-slide="next">
    <span class="carousel-control-next-icon" aria-hidden="true"></span>
    <span class="sr-only">Next</span>
  </a>
</div>

您好，很抱歉回复晚了，这对于调整图像大小很有用，但是上一个和下一个按钮会根据图像大小而变化，它们保持与最初相同，任何想法
你可以试试carousel-item修复高度
