css3 3D

css3 3D总结

1.学习css3 3D首先要知道 X轴 Y轴 Z轴对应的方向看下面的图片吧。

2.大家需要了解下这几个属性rotateX()、rotateY()、rotateZ();

rotateX()、rotateY()、rotateZ()
rotateX():对应的是3D的X轴，rotateX(45deg)是在X轴上旋转45度。
rotateY():对应的是3D的Y轴，rotateY(45deg)是在Y轴上旋转45度。
rotateZ():对应的是3D的Z轴，rotateZ(45deg)是在Z轴上旋转45度。

3.写的时候我们还有舞台和容器。分辨是perspective:，transform- style: preserve-3d;

perspective: 800px;对于舞台要加个视距，比如是800像素：
transform-style: preserve-3d;对于容器要加3D视图 要设置在父元素上：

4.下面给大家分享我做的案例。

html代码

<div class="b">
    <div class="box"><img src="img/zi1.png" alt=""></div>
    <div class="box1"><img src="img/zi2.png" alt=""></div>
</div>

css样式

 .b{
  	width: 300px;
      height: 300px;
      perspective: 800px; //视距
      transform-style: preserve-3d; //3d空间
      transform: rotateY(180deg);
      position: relative;
      margin: 50px auto;
      transition: 2s;
    }

    img{
      width: 100%;
      height: 100%;

    .b:hover{
      transform: rotateY(0deg);
