页面的head部分，需远程调用font-awesome图标字体库，并设置好页面元素的样式，代码如下：

<link rel='stylesheet prefetch' href='https://maxcdn.bootstrapcdn.com/font-awesome/4.5.0/css/font-awesome.min.css'>
<style type="text/css">
body {
  height: 100vh;
  width: 100%;
  display: flex;
  align-items: center;
  justify-content: center;
  background: linear-gradient(to left, #517fa4, #243949);
  font-family: 'Microsoft YaHei','Lantinghei SC','Open Sans',Arial,'Hiragino Sans GB','STHeiti','WenQuanYi Micro Hei','SimSun',sans-serif;
}

.card-container {
  perspective: 900px;
  margin-right: 20px;
}

.card {
  position: relative;
  width: 100px;
  height: 100px;
  transition: all 0.6s ease;
  transform-style: preserve-3d;
}

.front, .back {
  position: absolute;
  background: #7FC6A4;
  top: 0;
  left: 0;
  width: 100px;
  height: 100px;
  border-radius: 5px;
  color: white;
  box-shadow: 0 27px 55px 0 rgba(0, 0, 0, 0.3), 0 17px 17px 0 rgba(0, 0, 0, 0.15);
  backface-visibility: hidden;
}

.front {
  display: flex;
  align-items: center;
  justify-content: center;
  font-size: 30px;
}

.back {
  display: flex;
  align-items: center;
  justify-content: center;
  font-size: 18px;
}

.card-container:hover .card {
  transform: rotateY(180deg);
}

.back {
  transform: rotateY(180deg);
}
</style>

页面的body部分，需设置好不同图标按钮的div容器，代码如下：

<div class="card-container">
  <div class="card">
    <div class="front">
      <span class="fa fa-user"></span>
    </div>
    <div class="back">用户</div>
  </div>
</div>
<div class="card-container">
  <div class="card">
    <div class="front">
      <span class="fa fa-cogs"></span>
    </div>
    <div class="back">设置</div>
  </div>
</div>
<div class="card-container">
  <div class="card">
    <div class="front">
      <span class="fa fa-code"></span>
    </div>
    <div class="back">程序</div>
  </div>
</div>
