这里讲解实现抖音网红的正方体相册的动画制作(大正方体包裹小正方体，鼠标点击大正方体弹开展现小正方体)。  
  
**先上效果图：**

**1. 基础结构**  
老规矩，先写好基础结构。这里关于3D动画制作原理及正方体简单旋转制作的知识还不清楚的话可以参考我上一篇文章。首先父元素`cube`用来接收3D动画的视觉属性；然后`box`子元素包裹正方体内容并规定动画形式为3D；然后写进大正方体的6个面div和小正方体元素`inner-box`，并用flex将其定位于父元素`box`的中央；最后写进小正方体的6个面div。

**2. 样式形态**  
接下来就是主要的css部分。对于父级元素以及一些基础样式我就不重复讲解了，大小、图片、颜色等不定可根据个人喜好。主要是两个正方体的6个面，用`transform`属性将他们分别旋转和调节位置，以组成正方体结构。

.cube { 
        width: 200px;
        height: 200px;
        margin: 200px auto;
        perspective: 800px;
    }
    .box { 
        transform-style: preserve-3d;
        width: 100%;
        height: 100%;
        position: relative;
        display: flex;
        justify-content: center;
        align-items: center;
    }
    .child { 
        position: absolute;
        opacity: 0.8;
    }
    .child img { 
        width: 200px;
        height: 200px;
    }
    .child-th6{ 
        transform: rotateX(90deg) translateZ(100px);
    }
    .child-th5{ 
        transform: rotateX(-90deg) translateZ(100px);
    }
    .child-th4{ 
        transform: rotateY(-90deg) translateZ(100px);
    }
    .child-th3{ 
        transform: rotateY(90deg) translateZ(100px);
    }
    .child-th2{ 
        transform: translateZ(100px);
    }
    .child-th1{ 
        transform: rotateY(180deg) translateZ(100px);
    }
    .inner-box { 
        width: 90px;
        height: 90px;
    }
    .inner { 
        position: absolute;
        opacity: 0.8;
    }
    .inner img { 
        width: 90px;
        height: 90px;
    }
    .inner-box div:nth-child(1) { 
        transform: rotateY(180deg) translateZ(45px);
    }
    .inner-box div:nth-child(2) { 
        transform: translateZ(45px);
    }
    .inner-box div:nth-child(3) { 
        transform: rotateY(90deg) translateZ(45px);
    }
    .inner-box div:nth-child(4) { 
        transform: rotateY(-90deg) translateZ(45px);
    }
    .inner-box div:nth-child(5) { 
        transform: rotateX(-90deg) translateZ(45px);
    }
    .inner-box div:nth-child(6) { 
        transform: rotateX(90deg) translateZ(45px);
    }

**3. 基础动画**  
上面我们已经完成正方体的制作了，现在是静止的，需要我们添加上基础的旋转动画。这里我选择css3的`@keyframes`动画属性来实现。首先规定一个动画并赋予名字；然后在`box`元素上添加该动画，并设置相应的时间、自动播放、速率、反向等属性值。**注意，不要添加错地方，只能在`box`元素上，两个正方体才会同时转动。**

@keyframes cubeAction { 
        0% { 
            transform: rotateX(0) rotateY(0);
        }
        50% { 
            transform: rotateX(180deg) rotateY(180deg);
        }
        100% { 
            transform: rotateX(360deg) rotateY(360deg);
        }
    }
    .box { 
        transform-style: preserve-3d;
        width: 100%;
        height: 100%;
        animation: cubeAction 20s linear infinite alternate;
        position: relative;
        display: flex;
        justify-content: center;
        align-items: center;
    }

**4. 响应动画**  
做到这一步，你的正方体已经在原地360度地不停旋转了，那么就剩最后一步，为`box`元素添加`click`事件，使鼠标点击时大正方体的6个面同时弹开，展示小正方体。不难，只需要在响应函数中分别设置6个面的`transform`属性值就可以了。

大功告成！需要源码的可以拿去参考，有问题请留言交流：
