css手動(dòng)輪播圖

CSS手動(dòng)輪播圖是一種簡(jiǎn)單但實(shí)用的網(wǎng)頁(yè)設(shè)計(jì)元素,它能夠在網(wǎng)頁(yè)中創(chuàng)建動(dòng)態(tài)、引人注目的圖片輪播效果。為了實(shí)現(xiàn)這種效果,我們需要使用一些CSS代碼來(lái)定義輪播圖的樣式,并且還需要一些JavaScript代碼來(lái)控制輪播過(guò)程。下面是一個(gè)示例CSS手動(dòng)輪播圖的代碼。

<html>
<head>
	<style>
h1 {
text-align: center;
font-size: 30px;
color: #007acc;
margin-top: 30px;
}
.wrapper {
width: 500px;
height: 300px;
margin: 50px auto;
position: relative;
overflow: hidden;
}
.wrapper img {
width: 500px;
height: 300px;
position: absolute;
top: 0;
left: 0;
opacity: 0;
transition: all 1s ease-in-out;
}
.wrapper img.active {
opacity: 1;
z-index: 1;
}
.wrapper img.next {
opacity: 1;
z-index: 2;
transform: translateX(100%);
}
.wrapper .arrow {
width: 50px;
height: 50px;
background-color: #007acc;
position: absolute;
top: 50%;
transform: translateY(-50%);
cursor: pointer;
z-index: 3;
}
.wrapper .arrow.left {
left: 10px;
}
.wrapper .arrow.right {
right: 10px;
}
	</style>
</head>
<body>
	<h1>CSS手動(dòng)輪播圖</h1>
	<div class="wrapper">
<div class="arrow left"></div>
<div class="arrow right"></div>
	</div>
<script>
const images = document.querySelectorAll('.wrapper img');
const leftArrow = document.querySelector('.arrow.left');
const rightArrow = document.querySelector('.arrow.right');
let current = 0;
function reset() {
for (let i = 0; i < images.length; i++) {
images[i].classList.remove('active');
images[i].classList.remove('next');
}
}
function slideLeft() {
reset();
images[current].classList.add('next');
current = (current == 0) ? images.length - 1 : current - 1;
images[current].classList.add('active');
}
function slideRight() {
reset();
images[current].classList.add('next');
current = (current == images.length - 1) ? 0 : current + 1;
images[current].classList.add('active');
}
leftArrow.addEventListener('click', slideLeft);
rightArrow.addEventListener('click', slideRight);
	</script>
</body>
</html>

上面的代碼中,我們定義了一個(gè)包含三張圖片的輪播圖,以及兩個(gè)箭頭元素用于左右切換。CSS部分定義了輪播圖容器的大小、位置、背景、圖片樣式、箭頭樣式等。JavaScript部分實(shí)現(xiàn)了箭頭點(diǎn)擊事件,通過(guò)改變當(dāng)前激活圖片的類(lèi)名來(lái)實(shí)現(xiàn)圖片的輪播效果。
