悬停时旋转的背景变化效果 CSS3

Question

我是一名网络开发人员。对于我客户的网站，我需要对悬停特定 div 产生影响，如 website 所示。当我将鼠标悬停在 div 上时，背景应该通过旋转来改变。我怎样才能做到这一点。我只能使用 css3 过渡来缓和背景变化的效果。有没有什么方法可以不使用 jquery 来做同样的事情？

我模拟你提供的动画没有jquery。实现的关键是利用parent & chidl关系，理解动画播放的关键点

.hover{
  position: relative;
  width: 200px;
  height: 200px;
  background-color: #1cf;
}
.background{
  position: absolute;
  width: 100%;
  height: 100%;
  color: #fff;
  text-align: center;
  line-height:10;
  background-color: #c33;
  transition: all 0.3s;
  z-index: 2;
  font-size: 20px;
}
.content{
  position: absolute;
  width: 100%;
  height: 100%;
  background-color: #fff;
  text-align: center;
  font-size: 20px;
  opacity: 0;
  line-height: 10;
  transform: scale(-1,1);
  transition: all 0.3s;
}
.hover:hover .background{
  transform: scale(-1,1);
  opacity: 0;
}

.hover:hover .content{
  transform: scale(1,1);
  opacity: 1;
}
