In css3, you can use the animation attribute and the "@keyframes" rule to add a rotation animation to the image to rotate it
@keyframes It is a rule of CSS3 that can be used to define the behavior of a period of CSS animation and create simple animations.
The animation property is used to apply animation to a specified element; using different CSS animation properties, you can control many different aspects of the animation, including the number of animation iterations, whether it is starting Alternate between and end value, and whether the animation should run or pause. Animations can also delay their start time.
Syntax:
/* 定义动画*/
@keyframes 动画名称{
/* 样式规则*/
}
/* 将它应用于元素 */
.element {
animation-name: 动画名称（在@keyframes中已经声明好的）;
/* 或使用动画简写属性*/
animation: 动画名称 1s ...
}To define a rotation animation, you need to use the transform attribute; use transform: rotate (rotation angle) in the "@keyframes" rule Just control the rotation.

<meta charset="utf-8">

img {
margin: 100px;
animation: mymove 5s infinite;
-webkit-animation: mymove 5s infinite; /* Safari and Chrome */
