做这个案例之前首先要大概了解CSS的transform的属性
transform 属性向元素应用 2D 或 3D 转换。该属性允许我们对元素进行旋转、缩放、移动或倾斜。
看看效果图
打开的时候自动旋转，当鼠标经过的时候加快旋转速度，鼠标移开就恢复原来的速度。
参考代码：（为了美观可以自已加上一直背景图，我这里是空白的背景显得单调）
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>动画</title> <link rel="stylesheet" type="text/css" href="css/animate1.css"/> </head> <body> <div></div> <div id="one"> <div class="sj"> </div> <div class="ye"> </div> <div class="ye1"> </div> <div class="re"> </div> <div class="blue"> </div> <div class="blue1"> </div> <div class="green"> </div> <div class="green1"> </div> </div> <div id="mg"> </div> <div> <!--<img src="img/1.jpg" id="img"/>--> </div> </body> </html>
css:(还有更加简单的方法画出这个风车的，我这里复杂了一点，比较笨重，不够简洁)
