文中的img标签全部变成了macdown格式
一.什么是2D和3D
1.什么是2D和3D
2D就是一个平面,只有宽度和高度,没有厚度
3D就是一个立体,有宽度和高度,还有厚度
默认情况下所有的元素都是呈2D展现的
2.如何让某个元素呈3D展现
和透视一样,想看到某个元素的3d效果,只需要给他的父元素添加一个transform-style属性,然后设置为preserve-3d即可
3.transform-style的取值:
flat:默认取值,二维的;
preserve-3d:3D效果;

*{margin:0;padding:0;}
.father{width:200px;height:200px;
background-color:red;border:1pxsolid#000;margin:100pxauto;
perspective:500px;transform-style:preserve-3d;
transform:rotateY(0deg);
}.son{width:100px;height:100px;background-color:blue;border:1pxsolid#000;margin:0auto;margin-top:50px;transform:rotateY(45deg);}</style></head><body><pclass="father"><pclass="son"></p></p></body></html>
二.正方体(有瑕疵,页面文字显示有问题)

正方体(有瑕疵,仅供了解)
三.正方体(终极方案)
旋转90度后,坐标系也跟着旋转了90度,故应该沿着z轴移动;
立体效果攻略:先旋转一定的度数,再沿z轴平移
