html - 在不移动任何其他东西的情况下增加一个 div

Question

我有 4 个 div(红、黄、绿、蓝)就我而言，我每行有 2 个。我需要在红色下方不留空隙的情况下种植第二个(黄色)，只有蓝色必须向下跟随黄色。

我有一支密码笔如果你想试试。 Code

<div id="app">
  <v-app id="inspire">
    <v-item-group>
      <v-container>
        <div class="row">
          <v-col
            v-for="(item, index) in colors"
            :key="index"
            cols="12"
            md="6"
          >
              <v-card
                class="align-center"
                height="auto"
                :color="item.color"
              >
                <v-card-text v-for="(c, ind) in item.content" :key="ind" @click="colors[index].content.push(c)">{{c}}</v-card-text>
              </v-card>
          </v-col>
        </div>
      </v-container>
    </v-item-group>
  </v-app>
</div>

new Vue({
  el: '#app',
  vuetify: new Vuetify(),
  data: {
    colors: [{color: 'red', content: ['sample content']},
            {color: 'yellow', content: ['sample content']},
            {color: 'green', content: ['sample content']},
            {color: 'blue', content: ['sample content']}]
  }
})

div可以不加空格地增长，需要使用display : flex和flex direction

In the below code, I've considered tow columns of colors growing vertically

你可以有N种颜色
