实例4:

backface-visibility属性决定元素旋转背面是否可见,对于未旋转的元素,该元素是正面面向我们的,但是当其Y轴旋转约180度时会导致元素的背面面对观众。
backface-visibility基本语法如下:
backface-visibility: visible | hidden
visible含义是:为backface-visibility的默认值,表示反面可见
hidden含义是:表示反面不可见。
backface-visibility属性可用于隐藏内容的背面。默认情况下,背面可见,这意味着即使在翻转后,旋转的内容仍然可见。但当backface-visibility设置为hidden时,旋转后内容将隐藏,因为旋转后正面将不再可见。

HTML:

 1 <div class="backface-visibility">
