如何在离子卡上添加带数字的圆圈 header

Question

我试图制作一些带有编号的卡片（圆圈内有数字），但似乎有些不对劲。我不能把它做成圆形和中心

Here's what I want but when I try to make it, it become like this

这是我的一些代码，

<ion-card-header style="padding:0px;border-bottom:1px solid #9c9c9c;">
  <ion-row>
    <ion-col class="numberCircle">1</ion-col>
    <ion-col>John Doe</ion-col>
    <ion-col>Posting</ion-col>
  </ion-row>
</ion-card-header>

css

.numberCircle {
        border-radius: 50%;
        width: 25px;
        height: 25px;
        padding: 4px;
    
        background: #fff;
        border: 2px solid #666;
        color: #666;
        text-align: center;
    
        font: 12px Arial, sans-serif;
    }

将数字放在另一个元素中并将其居中会更容易

ion-row.row {
    padding: 5px 26px;
    justify-content: space-between;
}

ion-row.row ion-col {
   flex-grow: 0;
}

.numberCircle {
    border-radius: 50%;
    width: 25px;
    height: 25px;
    display: inline-flex;
    background: #fff;
    border: 2px solid #666;
    flex-grow: 0;
    padding: 0;
}

.numberCircle span {
    color: #666;
    text-align: center;
    font: 12px Arial, sans-serif;
    width: 25px;
    display: inline-block;
    margin: auto;
}

<ion-card-header style="padding:0px;border-bottom:1px solid #9c9c9c;">
  <ion-row>
    <ion-col class="numberCircle">
      <span>
          1
      </span>
    </ion-col>
    <ion-col>John Doe</ion-col>
    <ion-col>Posting</ion-col>
  </ion-row>
</ion-card-header>
