纯CSS是怎么实现图片左右翻转的?
导读
CSS 翻转图片主要用到的技术除了3D翻转和定位 ,还用到了一个属性 backface-visibility:visable|hidden;
该属性主要是用来设定元素背面是否可见。
效果图如下:
具体的步骤如下:
1、写出页面主体,
<div> <img src="Images/b.jpg" alt=""> <img src="Images/c.jpg" alt=""> </div>
2、通过定位使两张图片叠加在一起
div img { width: 250px; height: 170px; position: absolute; top: 0; left: 0; transition: all 1s; }
3、设置第一张图片背面不可见
div img:first-child { z-index: 1; backface-visibility: hidden; }
4、添加旋转180度
div:hover img { transform: rotateY(180deg); }
完整代码:
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <title>Document</title> <style> /* backface-visibility */ div { width: 250px; height: 170px; margin: 100px auto; position: relative; } div img { width: 250px; height: 170px; position: absolute; top: 0; left: 0; transition: all 1s; } div img:first-child { z-index: 1; backface-visibility: hidden; } div:hover img { transform: rotateY(180deg); } </style> </head> <body> <div> <img src="Images/b.jpg" alt=""> <img src="Images/c.jpg" alt=""> </div> </body> </html>
