旋转/缩放/倾斜/移动
1 .wrapper .wrap-box { 2 padding: 20px; 3 } 4 5 .box { 6 200px; 7 height: 200px; 8 background-color: yellow; 9 transition: all 1s; 10 11 } 12
通过 rotate() 方法，元素可以实现旋转效果，允许负值，元素将逆时针旋转。
使用方法如：transform: rotate(45deg)、transform: rotate(-90deg)
13 /*旋转*/ 14 .rotate:hover .box { 15 transform: rotate(360deg); 16 } 17 18 /*缩放*/ 19 .scale:hover .box { 20 transform: scale(0.5); 21 } 22 23 /*倾斜*/ 24 .skew .box { 25 transform: skew(45deg); 26 } 27 28 /*移动*/ 29 .translate:hover .box { 30 transform: translate(400px) rotate(90deg) scale(1.5); 31 }

定义和用法
backface-visibility 属性定义当元素不面向屏幕时是否可见。
如果在旋转元素不希望看到其背面时，该属性很有用。
