示例

旋转元素 transform-rotate

<style>
   .box {
     width: 200px;
     height: 200px;
     line-height: 200px;
     border: 1px solid green;

     text-align: center;
     margin: 0 auto;
   }

   .box + .box {
     margin-top: 100px;
   }

   .rotate {
     transform: rotate(45deg);
   }
 </style>

 <div class="box">正常元素</div>

 <div class="box rotate">旋转45deg</div>

实现效果
在这里插入图片描述

旋转过渡

.rotate {
  transition: transform 0.5s ease-in-out;
}

.rotate:hover {
  transform: rotate(45deg);
}

旋转动画

.rotate {
 animation: rotate-ani 2s linear infinite;
}

@keyframes rotate-ani {
 from {
   transform: rotate(0deg);
 }
 to {
   transform: rotate(360deg);
 }
}
