Html 更改离子标签上的离子高度

我想改变离子标签的高度。我进入_variables.scss并更改选项卡高度：

$tabs-height:                     200px !default;

但它不起作用。这是我的密码：

    <ion-tab title="Clienti" icon-on="ion-ios-body" icon-off="ion-ios-body-outline">
        <ion-view id="clienti" class="tabView">

        </ion-view>
    </ion-tab>

    <ion-tab title="Dati" icon-on="ion-ios-briefcase" icon-off="ion-ios-briefcase-outline">
        <ion-content class="tabView" has-bouncing="false">
            <div class="ca"></div>
        </ion-content>
    </ion-tab>

</ion-tabs>

如果你能用css来做的话。然后我做了这个

<ion-tab title="Clienti" icon-on="ion-ios-body" icon-off="ion-ios-body-outline" class="top-44">
      <ion-view id="clienti" class="tabView">

      </ion-view>
</ion-tab>

<ion-tab title="Dati" icon-on="ion-ios-briefcase" icon-off="ion-ios-briefcase-outline">
      <ion-content class="tabView" has-bouncing="false">
            <div class="ca"></div>
      </ion-content>
</ion-tab>
