网页轮播图
网页轮播图@FishC 嗨！要制作一个网页轮播图，你可以使用HTML、CSS和JavaScript来实现。下面是一个简单的例子：HTML代码：
<div class="slider">
<img src="img1.jpg" alt="Image 1">
<img src="img2.jpg" alt="Image 2">
<img src="img3.jpg" alt="Image 3">
</div>
CSS代码：
.slider {
width: 500px;
height: 300px;
overflow: hidden;
position: relative;
}
.slider img {
width: 100%;
height: 100%;
position: absolute;
top: 0;
left: 0;
opacity: 0;
transition: opacity 0.5s ease-in-out;
}
.slider img.active {
opacity: 1;
}
JavaScript代码：
window.onload = function() {
var slider = document.querySelector('.slider');
var images = slider.getElementsByTagName('img');
var currentIndex = 0;
setInterval(function() {
images.className = '';
currentIndex = (currentIndex + 1) % images.length;
images.className = 'active';
}, 2000);
};
在上面的代码中，`.slider`是一个具有指定宽度和高度的容器。`.slider img`是轮播图中的每个图片元素。通过设置`position: absolute;`属性，让图片重叠在一起，并且初始时只显示第一张图像。然后，通过JavaScript代码中的`setInterval`函数，循环切换每张图片的`active`类名，并使用CSS过渡效果。
请记得将`img1.jpg`，`img2.jpg`和`img3.jpg`替换为你自己的图片路径，并根据需要调整容器的宽度和高度。希望这可以帮助到你，祝你编程愉快！
