我想了解如何在悬停时制作旋转或旋转图像.我想知道如何在以下代码中使用 CSS 模拟该功能:

img {边界半径:50%；}

<img src="http://i.imgur.com/3DWAbmN.jpg"/>
 解决方案 
您可以使用 CSS3 过渡和 rotate() 来在悬停时旋转图像.
旋转图片:
img {过渡:转换 .7s 缓进出；}图像:悬停{变换:旋转(360度)；}

I want to find out how to make a spinning or rotating image when it is hovered. I would like to know how to emulate that functionality with CSS on the following code :



img {
  border-radius: 50%;
}

<img src="http://i.imgur.com/3DWAbmN.jpg" />



 解决方案 
You can use CSS3 transitions with rotate() to spin the image on hover.
Rotating image :


img {
  transition: transform .7s ease-in-out;
}
img:hover {
  transform: rotate(360deg);
}
