backface-visibility 3D修复

backface-visibility  是作用于 3D transform 时候

 

默认是   backface-visibility: hidden;

 

当一个元素3D变换的时候，会立即看到背面的内容，有时候会影响效果

 

设为  backface-visibility: hidden  就不会在3D动画效果时看到背面的内容

 

Firefox 10+ and IE 10+ support backface-visibility with no prefix. Opera (post Blink, 15+), Chrome, Safari, iOS, and Android all need -webkit-backface-visibility.
