使用 css 网格的垂直和水平居中 4x4 方形网格

Question

我想使用 divs 和 css-grid 编写 2048 游戏。这就是我想象的输出：

我有适合浏览器的外部部分window，我只想在中左div的中间（水平和垂直）写4x4网格（称为game-container)

<div class = "game-container">
  <div class = "game">
    <div class = "game-cell"></div>
    <!-- 16 game cells total -->
    <div class = "game-cell"></div>
  </div>
</div>

我使用以下方法制作了一个 4x4 网格：

div.game {
  display: grid;
  grid-template-columns: repeat(4, 1fr);
  grid-template-rows: repeat(4, 1fr);
}

但是，我有一些问题：

如何制作每个 game-cell 正方形（比如 50px）
如何在一个中间显示数字game-cell
如何让 div 相互接触

我可以做每一个，但不能一次全部做。

另外，如何在game-containerdiv.

中间（如图）显示gamediv

PS。我不介意使用一些 Bootstrap 如果它能简化某些事情。

关于外箱的一些信息：

html, body, div.container{
    height: 100%;
    margin: 0;
    padding: 0;
}

div.container {
  display:grid;
  grid-template-rows: 3fr 9fr 2fr;
  grid-template-columns: 3fr 5fr;
  grid-gap: 2px;
  background-color: yellow;
}

Answer 1

使用flexbox在grid外实现

div.game {
  display: grid;
  width: 50vw;
  height: 50vh;
  grid-template-columns: repeat(4, 1fr);
  grid-template-rows: repeat(4, 1fr);
  width: 120px;
  height: 120px
}

.game-cell {
  width: 30px;
  height: 30px;
  border: 1px solid ;
  box-sizing: border-box;
}

.left-half{
  width: 50vw;
  height: 100vh;
  border: 1px solid red;
  display: flex;
  align-items: center;
  justify-content: center;
}

body{
  padding: 0;
  margin: 0;
}

      <div class="game-cell"></div>
      <div class="game-cell"></div>
      <div class="game-cell"></div>

Answer 2

将此添加到您的 .game-container css

 display: flex;
 align-items: center;
 justify-content: center;

.game {
  display: grid;
  width: 120px;
  height: 120px;
  border:1px solid black;
}

.game-container{
    height: 500px;
    width: 500px;
    display: flex;
    align-items: center;
    justify-content: center;
    border: 1px solid black;
}

<div class = "game-container">

    <div class = "game">
     
    </div>

</div>
