html - 如何将此滑块调整到特定的高度/宽度

问题描述

我在响应式图像幻灯片上关注本教程，我进入教程时认为我可以将幻灯片调整到一定的高度和宽度，使其更小并适合我想要做的想法。可悲的是，我被卡住了，无法找到解决方法，所以我来到这里希望能解决这个问题。

这是我正在尝试做的图片

在此处输入图像描述

这是我的 HTML

解决方案

您可以使用 flex 容器并最终在动画上设置延迟，这样它们就不会同时开始。

如果我理解的话，可能的例子。

body{margin:0;}

section {
  display: flex;
  height: 100vh;
  gap: 5vw;
  padding: 5vw;
  box-sizing: border-box;
}

.slide-container {
  position: relative;
  flex-grow: 1;
  background:lightgray;
  overflow: hidden;
}

.slide-container .slider {
  position: absolute;
  top: 0;
  left: 0;
  width: 500%;
  height: 100%;
  float: left;
  animation: animate 10s linear infinite;
  }

.slide-container  + .slide-container .slider {
animation-delay:-3.3s;
}.slide-container  +.slide-container  + .slide-container .slider {
animation-delay:-6.6s;
}

.slide-container .slider .slide {
  position: relative;
  width: 20%;
  height: 100%;
  float: left;
}

.slide-container .slider .slide .caption {
  position: absolute;
  bottom: 6px;
  left: 6px;
  right: 6px;
  padding: 3px;
  background: rgba(0, 0, 0, 0.5);
  box-sizing: border-box;
}

.slide-container .slider .slide .caption h2 {
  margin: 0 0 20px;
  padding: 0;
  color: white;
  font-size: 48px;
}

.slide-container .slider .slide .caption p {
  margin: 0;
  padding: 0;
  color: white;
  font-size: 18px;
}

.slide-container .slider .slide.slide1 {
  background: url(https://picsum.photos/id/1012/400/280);
  background-size: cover;
  background-position: center;
}

.slide-container .slider .slide.slide2 {
  background:  url(https://picsum.photos/id/1014/400/280);
  background-size: cover;
  background-position: center;
}

.slide-container .slider .slide.slide3 {
  background:  url(https://picsum.photos/id/1016/400/280);
