css - 在css中创建盒子模型

我需要一点帮助。

我想像图像中那样创建盒子模型，有人可以帮我吗。

我已经写过代码，但是我不知道如何做得更好。

image

.container {
  display: flex;
  justify-content: flex-start;
  flex-direction: row;
  flex-wrap: wrap;
}

.card {
 background: #cecdcd;
  color: #000;
  position: relative;
  width: 110px;
  height: 110px;
  margin: 10px;
  overflow: hidden;
  word-wrap: break-word;
  border-radius: 10px;
  transition: 200ms;
}

<div class="container">
  <div class="card">
  </div>
   <div class="card">
  </div>
   <div class="card">
  </div>
   <div class="card">
  </div>
   <div class="card">
  </div>
   <div class="card">
  </div>
   <div class="card">
  </div>
   <div class="card">
  </div>
   <div class="card">
  </div>
   <div class="card">
  </div>
   <div class="card">
  </div>
</div>
