前言
用Vue来写了 移动端 3D轮播 带缩略图 ,在加 动画翻卡效果 ，其实也不是太难吧，也就做了一下午，哈哈，
船到桥头自然直，这样才可以，
首先看下做好的效果图
可以 点击 滑动 ，可以触摸滑动， 可以点击 缩略图滑动， 最后 在点击那个 选中的 翻卡的 那个有翻卡 的3D效果
代码：
<template>
<section class="container">
<div id="slide" class="slide index-slide">
<!-- 轮播图片数量可自行增减 -->
<div
class="img back"
v-for="(item,index) in imgsList"
:key="index + '-img'"
:class="'img'+ (index+1) "
:ref="'imgs'+(index)"
:id="'img'+(index)"
>
<img :src="item.img" :ref="'innderImgs'+(index)">
</div>
<div
class="img front"
v-for="(item,index) in imgFront"
:key="index"
:class="'img'+ (index+1) "

翻卡：
原理:这个卡片翻转效果是利用背面的内容一开始就先翻转180度,等正面翻转的时候背面再翻转360度,这样子背面翻转到面对屏幕的时候内容却是正的而不是反的
代码解析:
这里主要用到了CSS3的一些新的属性:perspective;
backface-visibility:hidden;
transition:all 2s;
transform:rotateY(Ndeg);
下面对这些属性进行详细的说明.
1.perspective:number|none(默认)
主要用来表示3D元素距离视图的距离,单位是像素,定义在父元素上,子元素就会获得透视效果,目前浏览器都在不支持,chrom和safari支持扩展的-webkit-perspectiv.
这个属性能查到的资料上基本上都是这么讲的,感觉不是很理解什么事透视效果,在我看来,使用这个属性就是在3D转换的时候能够看到立体的3D效果,可以配合perspective-origion来使用,可惜的是目前只有chrom和safari支持带有浏览器属性前缀的该属性.
2.backface-visibility:visiale|hidden
该属性用来定义当元素不面向屏幕的时候是否可见,可用来设置旋转元素是否希望用来看到背面.IE10+和Firefox支持该属性,Opera 15+、Safari 和 Chrome 支持替代的 -webkit-backface-visibility 属性
3.transition:css属性名称 完成动画的时间 规定速度效果的速度曲线 定义过渡效果何时开始
transition是一个简写属性,用来设置四个属性:transition-property, transition-duration, transition-timing-function, transition-delay,一般为了省事直接就会写作transition:all 2s。过渡时间必须设置，否则不会产生过渡效果。IE10+,chrome,opera,Firefox支持transition属性,Safari支持替代的-webkit-transition属性
transition-timing-function:linear(匀速)|ease(默认.慢速开始,加快,慢速结束)|ease-in(慢速开始)|ease-out(慢速结束)|ease-in-out(慢速开始,慢速结束)|cubic-bezier(n,n,n,n)贝赛尔曲线
4.transform:rotateY(Ndeg)
兼容性不说那么多了,感觉反正用的时候全部加上浏览器前缀好啦.
主要是用来定义各种变换的,translate,scale,rotate,skew,可惜熟悉使用一下,用的还是比较多的
这就是 2019年最后一遍博客啦，
来年咱们继续加油呀 ，奋斗的少年
永远在路上
