Question

我试图在由三角形组成的六边形中创建折叠效果。到目前为止，我只设法使三角形翻译而不是折叠。我要让

你需要创建一个三维旋转的动画。

既然是有点硬，我已经做了只有一次，并再利用它为在其它元件中，做旋转在平面

第一2个参数在ROTATE3D的DOM设置的中间元件是罪（60deg）和cos（60deg），以使旋转轴是在60℃下

@keyframes flip { 
 
    0%  { transform: rotate3d(0.5, 0.866, 0, 90deg); 
 
       opacity: 0;} 
 
    0.1%  { transform: rotate3d(0.5, 0.866, 0, 90deg); 
 
       opacity: 1;} 
 
    14%  { transform: rotate3d(0.5, 0.866, 0, 0deg); } 
 
    50%  { transform: rotate3d(-0.5, 0.866, 0, 0deg); } 
 
    63.99% { transform: rotate3d(-0.5, 0.866, 0, -90deg); 
 
       opacity: 1;} 
 
    64%, 100% { transform: rotate3d(-0.5, 0.866, 0, -90deg); 
 
       opacity: 0} 
 
} 
 

 
.folding-hex { 
 
    height: 69.28px; 
 
    width: 80px; 
 
    position: relative; 
 
    margin: 0 auto;
