一.什么是2D和3D
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; <htmllang="en"><head><metacharset="UTF-8"><title>106-3D转换模块</title><style> *{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>
