今天小编跟大家讲解下有关纯CSS绘制3D立方体，相信小伙伴们对这个话题应该有所关注吧，小编也收集到了有关纯CSS绘制3D立方体的相关资料，希望小伙伴们看了有所帮助。

本篇记录的是使用css3绘制3D立方体，并旋转起来。我的思路：1首先，用div元素画6个正方形摞在一起放在画布中间。为了区分，分别给每个div选择了不同的颜色，并且设置为半透明方便透视。2将6个div元素分为三组（上下一组、左右一组、前后一组），想象以画布中心为圆点，使三组分别沿x/y/z轴旋转90度。3上下一组，一张向上推50%正方形边长，一张向下推50%正方形边长；左右同理向左右推50%边长，前后同理向前后推50%边长。4整体旋转展示。html代码&css样式布局：<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title></title><style>.container {width: 400px;height: 400px;border: 1px solid #cccccc;} .box {position: relative;width: 100px;height: 100px;margin: auto;margin-top: 150px;transform-style: preserve-3d;} .box div {position: absolute;top: 0;left: 0;width: 100%;height: 100%;opacity: .5;transform-origin: center;} .box div:nth-of-type(1) { } .box div:nth-of-type(2) {background-color: yellow;} .box div:nth-of-type(3) {background-color: green;} .box div:nth-of-type(4) {background-color: blue;} .box div:nth-of-type(5) {background-color: black;} .box div:nth-of-type(6) {background-color: darkmagenta;}</style></head><body> <div class="container"><div class="box animate"><div></div><div></div><div></div><div></div><div></div><div></div></div></div></body></html>

css3添加6个正方形的动画效果

.box.animate div {animation: ease 4s 0s infinite;} .box.animate div:nth-of-type(1) {animation-name: box1-move;} .box.animate div:nth-of-type(2) {animation-name: box2-move;} .box.animate div:nth-of-type(3) {animation-name: box3-move;} .box.animate div:nth-of-type(4) {animation-name: box4-move;} .box.animate div:nth-of-type(5) {animation-name: box5-move;} .box.animate div:nth-of-type(6) {animation-name: box6-move;} @keyframes box1-move {0% {transform: rotatex(0deg);}25% {transform: rotatex(90deg);}50% {transform: rotatex(90deg) translatez(50px);}100% {transform: rotatex(90deg) translatez(50px);}} @keyframes box2-move {0% {transform: rotatex(0deg);}25% {transform: rotatex(90deg);}50% {transform: rotatex(90deg) translatez(-50px);}100% {transform: rotatex(90deg) translatez(-50px);}} @keyframes box3-move {0% {transform: rotatex(0deg);}25% {transform: rotatey(90deg);}50% {transform: rotatey(90deg) translatez(50px);}100% {transform: rotatey(90deg) translatez(50px);}} @keyframes box4-move {0% {transform: rotatex(0deg);}25% {transform: rotatey(90deg);}50% {transform: rotatey(90deg) translatez(-50px);}100% {transform: rotatey(90deg) translatez(-50px);}} @keyframes box5-move {0% { }25% {transform: translatez(0px);}50% {transform: translatez(50px);}100% {transform: translatez(50px);}} @keyframes box6-move {0% { }25% {transform: translatez(0px);}50% {transform: translatez(-50px);}100% {transform: translatez(-50px);}}

添加整提旋转动画

.box.animate {animation: box-move ease 4s 0s infinite;} @keyframes box-move {0% {transform: rotatex(0deg) rotatey(0deg)}50% {transform: rotatex(45deg) rotatey(45deg)}100% {transform: rotatex(405deg) rotatey(405deg)}}

动画转的我有点头晕，所以我决定把.animate类名剥离出来，用JavaScript通过按钮触发的模式将.animate添加到DOM中去，这样，只有点击按钮后动画才会被触发。最后，我添加了两个按钮，move和stop，分别用来触发动画和使动画停止。

<div class="ope"><button id="animate">Move</button><button id="stop">Stop</button></div> .ope {margin-top: 100px;text-align: center;} .ope button {margin: 0 10px;border: 1px solid #4380f5;border-radius: 5px;cursor: pointer;background-color: #4380f5;color: #ffffff;outline: none;} .ope button:hover {background-color: #3e76e3;} .ope button:active {background-color: #3361ba;} <script>(function () {var box = document.getElementsByClassName('box')[0]; document.getElementById('animate').onclick = function () {box.className = 'box animate';}document.getElementById('stop').onclick = function () {box.className = 'box';}})();</script>
