transfrom
(1) 坐标 x y z
(2) 变形 基点位置 transform-origin
(3)transfrom-style:preserve-3d

它就用到了一个比较简单的坐标y 轴旋转那咱们看一下他的代码
html的代码:
<p class="kj" id="kj"> <p class="mian"><img src="img/p1.jpg" alt=""></p> <p class="mian"><img src="img/p2.jpg" alt=""></p> <p class="mian"><img src="img/p3.jpg" alt=""></p> <p class="mian"><img src="img/p4.jpg" alt=""></p> <p class="mian"><img src="img/p5.jpg" alt=""></p> <p class="mian"><img src="img/p6.jpg" alt=""></p> <p class="mian"><img src="img/p7.jpg" alt=""></p> <p class="mian"><img src="img/p8.jpg" alt=""></p> <p class="mian"><img src="img/p9.jpg" alt=""></p> </p>
首先要建九个盒子放九张图片,这个很容易理解的。
css的代码
body{ background: #6daf39;(背景加了个颜色 主要是好看) } .xj{ perspective:600px;(这是井深) } .kj{ transition: 1s;(运动时间) transform-style:preserve-3d;(实现3d效果 当然这是非常重的) width:200px; height: 300px; margin:80px auto; position: relative; transform: rotateY(0deg) rotateX(0deg) translateZ(-275px); transform-origin: center center -275px; } .mian{ position:absolute; font-size: 50px; color:#fff; text-align: center; line-height: 300px; } .mian:nth-child(1){ width:200px; height: 300px; background: #ff2223; transform: rotateY(0deg)translateZ(275px); } .mian:nth-child(2){ width:200px; height: 300px; background: #ff2223; transform: rotateY(40deg)translateZ(275px); } .mian:nth-child(3){ width:200px; height: 300px; background: #ff2223; transform: rotateY(80deg)translateZ(275px); } .mian:nth-child(4){ width:200px; height: 300px; background: #ff2223; transform: rotateY(120deg)translateZ(275px); } .mian:nth-child(5){ width:200px; height: 300px; background: #ff2223; transform: rotateY(160deg)translateZ(275px); } .mian:nth-child(6){ width:200px; height: 300px; background: #ff2223; transform: rotateY(200deg)translateZ(275px); } .mian:nth-child(7){ width:200px; height: 300px; background: #ff2223; transform: rotateY(240deg)translateZ(275px); } .mian:nth-child(8){ width:200px; height: 300px; background: #ff2223; transform: rotateY(280deg)translateZ(275px); } .mian:nth-child(9){ width:200px; height: 300px; background: #ff2223; transform: rotateY(320deg)translateZ(275px); }
css就到这里,很简单的;
js的代码
kj.onclick=function () { cishu++; var jiaodu=40*cishu; kj.style.transform="rotateY("+jiaodu+"deg)translateZ(-275px)" }
(kj)就是3d空间,点击kj要是一种效果,就要有一种方法或步骤;
3d空间样式rotateY(这就是上下轴旋转)translateZ(Z这就是3d立体字轴;让3d空间后移275px找到轴心位置)
