How to add circle with number on ion card header

Question

I was trying to make some card with numbering(circle with number inside), but something seems wrong. I can't make it circle and center

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

Here is some of my code,

<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;
    }

It is easier when you put the number in another element and center that

 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>
