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         }

点击按钮，增加样式做动画

 1 <style>
 2         body {
 3             margin: 0;
 4             padding: 0;
 5         }

 7         .demo {
 8             width: 200px;
 9             height: 200px;
10             background-color: blue;
11             
12         }
13 
14         .child {
15             width: 30px;
16             height: 30px;
17             background-color: yellow;
18             transition: all 1s;
19         }
20 
21         .current .child {
22             width: 120px;
23             height: 120px;
24         }
25     </style>
26 </head>
27 <body>
28     <div class="demo">
29         <div class="child"></div>
30     </div>
31     <button id="btn">换色</button>
32     <script>
33         var button = document.getElementById('btn');
34         var demo = document.querySelector('.demo');
35 
36         button.addEventListener('click', function () {
37             demo.classList.add('current');
38         })
39     </script>

动态进度条：改变left值；

 1 <style>
 2         body {

14         .child {
15             width: 30px;
16             height: 30px;
17             background-color: yellow;
18             transition: all 1s;
19         }
20 
21         .current .child {
22             width: 120px;
23             height: 120px;

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。



            transition: all 0.6s;
        }
        .wallet::before {
            background: url(./images/bg.png) left top;
