html - 如何在 Bulma 中集中对齐列？

Question

我正在尝试使用以下布局创建一个基于磁贴的仪表板(无需使用 Bulma 磁贴):

<div class="container">
  <br>
  <div class="columns is-multiline">
    <div class="column is-3">
      <div class="box has-background-success">
        <p class="title has-text-centered">One</p>
        <div>
          <div class="columns ">
            <div class="column box is-5">A</div>
            <div class="column"></div>
            <div class="column box is-5">B</div>
            <div class="column"></div>
          </div>

          <div class="columns">
            <div class="column box is-5">C</div>
            <div class="column"></div>
            <div class="column box is-5">D</div>
            <div class="column"></div>
          </div>
        </div>
      </div>
    </div>

    <div class="column is-3">
      <div class="box has-background-danger">
        <p class="title has-text-centered">Two</p>
        <div>
          <div class="columns ">
            <div class="column box is-5">A</div>
            <div class="column"></div>
            <div class="column box is-5">B</div>
            <div class="column"></div>
          </div>

          <div class="columns">
            <div class="column box is-5">C</div>
            <div class="column"></div>
            <div class="column box is-5">D</div>
            <div class="column"></div>
          </div>
        </div>
      </div>
    </div>

    <div class="column is-3">
      <div class="box has-background-success">
        <p class="title has-text-centered">Three</p>
        <div>
          <div class="columns ">
            <div class="column box is-5">A</div>
            <div class="column"></div>
            <div class="column box is-5">B</div>
            <div class="column"></div>
          </div>

          <div class="columns">
            <div class="column box is-5">C</div>
            <div class="column"></div>
            <div class="column box is-5">D</div>
            <div class="column"></div>
          </div>
        </div>
      </div>
    </div>        
  </div>
</div>

但是我可以看到左边有一个缝隙，比盒子右边的缝隙小，每个盒子的底部也有一个缝隙。

如何确保内容很好地放置在每个框的中间？

.columns {
   flex-wrap: wrap; 
   justify-content: space-between
}
.column.is-5 {
height: 100%;
}
