本篇文章给大家带来的内容是关于css3D+动画的例子(附完整代码),有一定的参考价值,有需要的朋友可以参考一下,希望对你有所帮助。

前言

最近玩了玩用css来构建3D效果,写了几个demo,所以博客总结一下。  在阅读这篇博客之前,请先自行了解一下css 3D的属性,例如:transform-style,transform-origin,transform, perspective。

写一个简单的立方体

1、我们先用css实现一个长方体,一个长方体有6个边,我们写6个li,并用一个ul包裹起来,根据我写3D动画的经验,最好有一个父元素来包裹

<p class="parent">
    <ul>
        <li>1</li>
        <li>2</li>
        <li>3</li>
        <li>4</li>
        <li>5</li>
        <li>6</li>
    </ul>
</p>

2、先给.parent设置宽高,并且给他设置视距和基点位置。

.parent{
            width: 800px;
            height: 400px;
            border: 1px solid #000;
            margin: 0 auto;
            perspective: 2000px;
            perspective-origin: -40% -80%;
            background: #000;
        }

3、给ul设置宽高以及preserve-3d属性保留子元素3d转换,子元素li全部绝对定位

        ul{
            width: 50px;
            position: relative;
            margin: 100px auto;
            transform-style : preserve-3d;
        }
         li{
            width: 100px;
            height: 100px;
            background:  rgba(255, 255, 0, 0.3);
            position: absolute;
            text-align: center;           
            border: 3px solid greenyellow;
        }

效果如下图所示:

4、先写一个面,给他的背景设置 background:  rgba(255, 255, 0, 0.3);

 li:nth-child(1){
            background:  rgba(255, 255, 0, 0.3);
            transform:  translateY(50px) rotateX(90deg);
        }

效果如下图所示:

5、我们写好了第一个面,然后我们在将其他6个面调整好,变成下图所示。关于rotate的旋转方向这里不解释,不懂的朋友可以自行查看其他文档。

        /*上面*/
         li:nth-child(1){
            transform: translateY(-50px) rotateX(90deg);
        } 
        /*下面*/
        li:nth-child(2){
        
            transform:  translateY(50px) rotateX(90deg);
        }
        /*左面*/
        li:nth-child(3){
            transform: translateX(-50px) rotateY(90deg);
        }
        /*右面*/
        li:nth-child(4){
            transform: translateX(50px) rotateY(90deg);
        }
        /*前面*/
        li:nth-child(5){
            transform: translateZ(50px);
        }
        /*后面*/
        li:nth-child(6){
            transform: translateZ(-50px);
        }

效果如下图所示:

下面是两种css3D+动画的效果

1、代码如下:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>书页2</title>
    <style>
        .container{
            width: 1000px;
            height: 650px;
            background: #000;
            perspective: 2000px;
            border: 1px solid transparent;
            overflow: hidden;
            margin: 0 auto;
            perspective-origin: 10% 20%;
           
        }
    
        .cube{
            width: 200px;
            height: 300px;
            transform-style: preserve-3d;
            margin:100px auto;
            
            position: relative;
            transform: rotateX(30deg);
            border-radius: 50%;
            padding: 60px;
        }
        .mian{
            width: 200px;
            height: 300px;
            background-image: url(1.jpg);
            background-position:400px 0;
            position: absolute;
           
            border: 1px solid #ccc;
            transition: 2s;
        }
        /* .mian1:hover{
            transform-origin: right;
            transform: rotateY(-60deg);
        } */
        .mian1{
            transform-origin: right;
            transform: translateX(-200px) rotateY(45deg);
            background-position: 0 0;
        }
        .mian3{
            transform-origin: left;
            transform: translateX(200px) rotateY(45deg);
            background-position: 200px 0;
        }
        .mian3:hover{
            transform: translateX(200px) rotateY(0deg);
        } 
        .mian1:hover{
            transform: translateX(-200px) rotateY(0deg);
        }
    </style>
</head>
<body>
    <p class="container">
        <p class="cube">
            <p class="mian mian1"></p>
            <p class="mian mian2"></p>
            <p class="mian mian3"></p>
        </p>
    </p>
</body>
</html>

2、代码如下:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>立方体</title>

    <style>
        *{
            margin: 0;
            padding: 0;
            list-style: none;
        }
        .parent{
            width: 1000px;
            margin:  0 auto;
            height: 600px;
            background: black;
            perspective: 5000px;
            perspective-origin: -40% -120%;
            border: 1px solid #000;
        }
        ul{
            width: 100px;
            height: 300px;
            position: relative;
            margin:100px auto;
            transform-style: preserve-3d;
            animation: zuan 3s linear infinite;
            border: 1px solid greenyellow;
        }

        li{
            width: 100px;
            height: 300px;
            background:  rgba(0, 0, 0, 0.5);
            position: absolute;
            text-align: center;
            line-height: 100px;
            
            border: 3px solid greenyellow;
        }
        li:nth-child(1){
            transform: rotateY(30deg) translateZ(-200px);
      
        }
        li:nth-child(2){
            transform: rotateY(60deg) translateZ(-200px);
            background:  rgba(255, 0, 0, 0.5);
        }
        li:nth-child(3){
            transform: rotateY(90deg) translateZ(-200px);
            
        }
        li:nth-child(4){
            transform: rotateY(120deg) translateZ(-200px);
            background:  rgba(0, 0, 255, 0.5);
        }
        li:nth-child(5){
            transform: rotateY(150deg) translateZ(-200px);
            
        }
        li:nth-child(6){
            transform: rotateY(180deg) translateZ(-200px);
            background:  rgba(255, 0, 255, 0.5);
        }
        li:nth-child(7){
            transform: rotateY(210deg) translateZ(-200px);
      
        }
        li:nth-child(8){
            transform: rotateY(240deg) translateZ(-200px);
            background:  rgba(0, 255, 0, 0.5);
        }
        li:nth-child(9){
            transform: rotateY(270deg) translateZ(-200px);
      
        }
        li:nth-child(10){
            transform: rotateY(300deg) translateZ(-200px);
            background:  rgba(0, 255, 255, 0.5);
        }
        li:nth-child(11){
            transform: rotateY(330deg) translateZ(-200px);
      
        }
        li:nth-child(12){
            transform: rotateY(360deg) translateZ(-200px);
            background:  rgba(255, 255, 255, 0.5);
        }

        @keyframes zuan{
            0%{
                transform: rotateY(0deg);
            }
            100%{
                transform: rotateY(360deg);
            }
        }
    
    </style>
</head>
<body>

    <p class="parent">
        <ul>    
            <li></li>
            <li></li>
            <li></li>
            <li></li>
            <li></li>
            <li></li>
            <li></li>
            <li></li>
            <li></li>
            <li></li>
