嗨，我正在尝试在这 4 张网站图像之间淡入淡出。到目前为止太好了，但是我试图更改此代码。有谁知道如何更改代码，以便每个图像在 5 秒后更改？任何帮助都非常感激

正如 litel 所说，引导轮播非常适合您的示例。W3 学校在这里有一个关于 Bootstrap 的很好的教程，这是我用来构建我的第一个轮播的教程。

但是为了在你现在的上下文中回答你的问题，我认为用一个简短的脚本而不是CSS动画来做到这一点要容易得多。我将以下代码添加到文档的末尾，这似乎可以满足您的要求。希望有帮助。

<style>
.image-wrapper .image{
    display: none; /*Hide the images to begin with*/
}
</style>
<script>
var currentImage = 0;
$(document).ready(function(){
imageChanger(); /*First image fades in on page ready*/
setInterval(imageChanger, 5000);}); /*set a timer of 5000ms for each subsequent image*/
function imageChanger(){
    $('.image-wrapper img').eq(currentImage).fadeOut();
    currentImage = (currentImage+1)%4;
    $('.image-wrapper img').eq(currentImage).fadeIn();
}
</script>
