.content {
    ion-grid {
        height: 100% !important;
    }
    .row1 {
        flex: 1 !important;
    }
    .row2 {
        flex: 1 !important;
    }
}

.html

<ion-content class="content">
  <ion-grid>
    <ion-row class="row1">
      <ion-col size="12">
          S-Works Venge Disc – SRAM eTAP
      </ion-col>
    </ion-row>
    <ion-row class="row2">
      <ion-col size="12">
        <ion-row>
          <ion-col size="12">
            S-Works Venge Disc – SRAM eTAP
          </ion-col>
        </ion-row>
        <ion-row>
          <ion-col size="12">
            Availability : Upon Request
          </ion-col>
        </ion-row>
        <ion-row>
          <ion-col size="12">

        <ion-row>
          <ion-col size="12">
            We aren't satisfied with second fastest. Hello, why do you think we have our own Win Tunnel and the motto,
            "Aero is Everything?" We live and breathe aero, because we know that aerodynamic optimization is the best
            thing we can do to make you faster. And this philosophy has never been truer than with the new Venge. Being
            eight seconds faster than the ViAS, it’s not only the most aerodynamic bike on the road, but it’s also lost
            460 grams. And now with SRAM RED eTAP, you’re definitively looking at the new shape of speed.
          </ion-col>
        </ion-row>
      </ion-col>
    </ion-row>
  </ion-grid>
</ion-content>

结果:

问:您能告诉我为什么在上述设计中我看不到 50:50 空间分配吗？

Answer 1

要使 flex: 1 属性起作用，其父级必须具有属性 display: flex默认情况下，display: flex 在一行中显示其子项，这就是我们需要将方向更改为列的原因

ion-grid {
    display: flex;
    flex-direction: column;
    height: 100% !important;
}
