我想把它变成这样： https://mobirise.com/bootstrap-carousel/

我该怎么做？

【问题讨论】：

您在示例中使用的是 Bootstrap 3，但使用 Bootstrap 4 标记了这个问题。什么给出了？
对错误感到抱歉。
添加 bootstrap-3 标签。否则没有人会发现你的问题。
我已经添加了标签。

标签： twitter-bootstrap-3 carousel

【解决方案1】：

将宽度设置为 100%，您甚至可以设置固定高度以保持一致性。

.carousel-inner img {
    width: 100%; /* Set width to 100% */
}

@media (min-width: 576px) { 
 .carousel-inner img {
  width: 100%; /* Set width to 100% */
  max-height:340px;
  }
}


@media (min-width: 768px) { 
  .carousel-inner img {
  width: 100%; /* Set width to 100% */
  max-height:720px;
  }
}


@media (min-width: 992px) { 
   .carousel-inner img {
  width: 100%; /* Set width to 100% */
  }
  .carousel-inner{
    max-height:580px;
  }
}


@media (min-width: 1200px) { 
    .carousel-inner img {
  width: 100%; /* Set width to 100% */
      max-height:700px;

  }
    .carousel-inner{
    max-height:700px;
  }

}

【讨论】：

谢谢。现在宽度为 100%。但是，我面临高度问题。当我包括“身高：80%；”在 .carousel-inner img 中，没有任何反应。如何降低图片的高度？
@john，应该使用媒体查询来完成。使用 % 将没有用，因为它仅在引用某些内容时才有效。我已经更新了答案，请检查，并会尽快添加简要说明。
