【问题描述】：

我有以下引导滑块

<div id="demo" class="carousel slide" data-ride="carousel">

  <!-- Indicators -->
  <ul class="carousel-indicators">
    <li data-target="#demo" data-slide-to="0" class="active"></li>
    <li data-target="#demo" data-slide-to="1"></li>
    <li data-target="#demo" data-slide-to="2"></li>
  </ul>

  <!-- The slideshow -->
  <div class="carousel-inner">
    <div class="carousel-item active">
      <img src="la.jpg" alt="Los Angeles" width="100%" height="100%">
    </div>
    <div class="carousel-item">
      <img src="chicago.jpg" alt="Chicago" width="100%" height="100%">
    </div>
    <div class="carousel-item">
      <img src="ny.jpg" alt="New York" width="100%" height="100%">
    </div>
  </div>

  <!-- Left and right controls -->
  <a class="carousel-control-prev" href="#demo" data-slide="prev">
    <span class="carousel-control-prev-icon"></span>
  </a>
  <a class="carousel-control-next" href="#demo" data-slide="next">
    <span class="carousel-control-next-icon"></span>
  </a>
</div>

我有不同高度的图像，如何使用封面功能使所有图像具有相同的高度和宽度以适合边框并具有封面中心效果？

这就是答案

<div id="demo" class="carousel slide" data-ride="carousel">

  <!-- Indicators -->
  <ul class="carousel-indicators">
    <li data-target="#demo" data-slide-to="0" class="active"></li>
    <li data-target="#demo" data-slide-to="1"></li>
    <li data-target="#demo" data-slide-to="2"></li>
  </ul>

  <!-- The slideshow -->
  <div class="carousel-inner">
    <div class="carousel-item active">
      <img src="la.jpg" alt="Los Angeles" width="100%" style="object-fit: cover; object-position: 50% 50%; height: 60vh">
    </div>
    <div class="carousel-item">
      <img src="chicago.jpg" alt="Chicago" width="100%" style="object-fit: cover; object-position: 50% 50%; height: 60vh">
    </div>
    <div class="carousel-item">
      <img src="ny.jpg" alt="New York" width="100%" style="object-fit: cover; object-position: 50% 50%; height: 60vh">
    </div>
   </div>

  <!-- Left and right controls -->
  <a class="carousel-control-prev" href="#demo" data-slide="prev">
     <span class="carousel-control-prev-icon"></span>
  </a>
  <a class="carousel-control-next" href="#demo" data-slide="next">
     <span class="carousel-control-next-icon"></span>
  </a>
 </div>

注意：object-git 不适用于 IE，object-position center center 不适用于所有浏览器
