animation: move 15s ease 1s infinite

This is a CSS animation shorthand property that sets the following animation properties:

- `move`: The animation's name or keyframes to be used.
- `15s`: The duration of the animation, which is set to 15 seconds.
- `ease`: The timing function used for the animation, which applies an easing effect that starts slow, then accelerates and ends slow.
- `1s`: The delay before the animation starts, which is set to 1 second.
- `infinite`: The number of times the animation should run, which is set to infinite or until it is stopped.

Overall, this animation will move an element in a certain way for 15 seconds, with a 1-second delay before it starts, and will repeat indefinitely.

使用 animation 动画实现一个简单的幻灯片效果

好的，以下是实现幻灯片效果的示例代码：

HTML 代码：

<div class="slideshow">
  <img src="image1.jpg" alt="image1">
  <img src="image2.jpg" alt="image2">
  <img src="image3.jpg" alt="image3">
</div>

CSS 代码：

.slideshow {
  position: relative;
  height: 400px;
  width: 600px;
  margin: 0 auto;
}

.slideshow img {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  opacity: 0;
  transition: opacity 1s ease-in-out;
}

.slideshow img:first-child {
  opacity: 1;
}

@keyframes slideshow {
  0% {
    opacity: 0;
  }
  20% {
    opacity: 1;
  }
  25% {
    opacity: 1;
  }
  45% {
    opacity: 0;
  }
  100% {
    opacity: 0;
  }
}

.slideshow img:nth-child(2) {
  animation-delay: 5s;
  animation-name: slideshow;
  animation-duration: 15s;
  animation-iteration-count: infinite;
}

.slideshow img:nth-child(3) {
  animation-delay: 10s;
  animation-name: slideshow;
  animation-duration: 15s;
  animation-iteration-count: infinite;
}

在上面的代码中，我们创建了一个 `.slideshow` 容器，其中包含了三个 `img` 元素，分别是三张图片。我们使用了 `position: absolute` 来将图片定位在容器的左上角，同时使用 `opacity` 来设置图片的透明度，初始值为 0。然后，我们使用了 `transition` 属性来设置图片的渐变动画。接着，我们使用了 `@keyframes` 规则来定义幻灯片动画的关键帧。最后，我们使用了 `animation` 属性来指定图片的动画名称、动画时长、动画延迟和动画次数。

在这个示例中，我们使用了三张图片来创建幻灯片效果，并设置了第二张图片和第三张图片的动画延迟时间，以实现图片轮播的效果。你可以根据需要调整动画效果和图片数量来实现不同的幻灯片效果。
