当窗口重新调整大小时，保持圆的纵横比

I have circles lined up using flexbox and they look decent on small screen width:

我有使用flexbox排列的圆圈,它们在小屏幕宽度上看起来很不错:

but as soon as I widen the width of my screen, they look really stretched. But I need them to be round from every prospect.

但是当我加宽屏幕的宽度时,它们看起来非常紧张。但是我需要他们来自每个前景。

I'm not sure maybe there is a way that fixes their displaying on different screen sizes. Maybe I could have used some media queries. How to handle this?

我不确定是否有办法可以修复不同屏幕尺寸的显示效果。也许我可以使用一些媒体查询。怎么办呢?

You have to set the width and height of your circle to the same value:

您必须将圆的宽度和高度设置为相同的值:

.dashboard-grey-menu {
  height: 30vh;
  background-color: #959595;
}
.circle {
  border-radius: 50%;
  width: 10vw;
  height: 10vw;
  background-color: #B7B7B7;
  margin: 20px;
}
.flex {
  display: flex;
  justify-content: center;
  align-items: center;
  height: 30vh;
  width: 100%;
}

<ion-content has-header="false">
  <div class="dashboard-grey-menu">
    <div class="flex row no-padding">
      <div class="col"><div class="circle"></div></div>
      <div class="col"><div class="circle"></div></div>
      <div class="col"><div class="circle"></div></div>
      <div class="col"><div class="circle"></div></div>
    </div>
  </div>
</ion-content>
