本篇记录的是使用CSS3绘制3D立方体,并旋转起来。
我的思路:
1️⃣ 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。
2️⃣ 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。
3️⃣ 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。
4️⃣ 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。
<!-- Html代码 --> <div class="ope"> <button id="animate">Move</button> <button id="stop">Stop</button> </div> <!-- CSS代码 --> .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; } <!-- JavaScript代码 --> <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>
