这组3D轮播图中图效果图演示6种轮播图

  这是一款js和CSS3 3D轮播图。这组3D轮播图中，共演示了6种轮播图效果。这些3D轮播图都是通过简单的JS代码配合CSS3来完成的。

  使用方法 HTML结构

  以8张图片的3D轮播图为例js实现图片3d效果轮播js实现图片3d效果轮播，它的基本HTML结构如下：

  CSS样式

  该3D轮播图的CSS样式如下：

.carousel {
 padding: 20px;
 -webkit-perspective: 500px;
perspective: 500px;
overflow: hidden;
 display: -webkit-box;
 display: -ms-flexbox;
 display: flex;
 -webkit-box-orient: vertical;
 -webkit-box-direction: normal;
 -ms-flex-direction: column;
flex-direction: column;
-webkit-box-align: center;
 -ms-flex-align: center;
align-items: center;
}
.carousel > * {
 -webkit-box-flex: 0;
 -ms-flex: 0 0 auto;
flex: 0 0 auto;
}
.carousel figure {
 margin: 0;
 width: 40%;
 -webkit-transform-style: preserve-3d;
transform-style: preserve-3d;
-webkit-transition: -webkit-transform 0.5s;
 transition: -webkit-transform 0.5s;
 transition: transform 0.5s;
 transition: transform 0.5s, -webkit-transform 0.5s;
}
.carousel figure img {
 width: 100%;
 box-sizing: border-box;
 padding: 0 0px;
}
.carousel figure img:not(:first-of-type) {
 position: absolute;
 left: 0;
 top: 0;
}
.carousel nav {
 display: -webkit-box;
 display: -ms-flexbox;
 display: flex;
 -webkit-box-pack: center;
 -ms-flex-pack: center;
justify-content: center;
margin: 20px 0 0;
}
.carousel nav button {
 -webkit-box-flex: 0;
 -ms-flex: 0 0 auto;
flex: 0 0 auto;
margin: 0 5px;
 cursor: pointer;
 color: #333;
 background: none;
 border: 1px solid;
 letter-spacing: 1px;
 padding: 5px 10px;
} 
 

  JavaScript

  最后通过js代码来控制该3D轮播图的图片切换。

'use strict';
window.addEventListener('load', function () {
 var carousels = document.querySelectorAll('.carousel');
 for (var i = 0; i < carousels.length; i++) {
carousel(carousels[i]);
}
});
function carousel(root) {
 var figure = root.querySelector('figure'),
 nav = root.querySelector('nav'),
  images = figure.children,
  n = images.length,
  gap = root.dataset.gap || 0,
  bfc = 'bfc' in root.dataset,
  theta = 2 * Math.PI / n,
  currImage = 0;
setupCarousel(n, parseFloat(getComputedStyle(images[0]).width));
 window.addEventListener('resize', function () {
setupCarousel(n, parseFloat(getComputedStyle(images[0]).width));
});
 setupNavigation();
 function setupCarousel(n, s) {
var apothem = s / (2 * Math.tan(Math.PI / n));
figure.style.transformOrigin = '50% 50% ' + -apothem + 'px';
for (var i = 0; i < n; i++) {
  images[i].style.padding = gap + 'px';
}for (i = 1; i < n; i++) {
  images[i].style.transformOrigin = '50% 50% ' + -apothem + 'px';
  images[i].style.transform = 'rotateY(' + i * theta + 'rad)';
}
if (bfc) for (i = 0; i < n; i++) {
  images[i].style.backfaceVisibility = 'hidden';
}rotateCarousel(currImage);
}
 function setupNavigation() {
nav.addEventListener('click', onClick, true);
function onClick(e) {
  e.stopPropagation();
  var t = e.target;
  if (t.tagName.toUpperCase() != 'BUTTON') return;
  if (t.classList.contains('next')) {
 currImage++;
  } else {
 currImage--;
  }
  rotateCarousel(currImage);
}
}
 function rotateCarousel(imageIndex) {
figure.style.transform = 'rotateY(' + imageIndex * -theta + 'rad)';
}
}
