Question

我正在使用ionic-v4，并创建了一个用于导航的ionic tabs页面应用程序。我现在想做的是在离子表中添加背景色，但是我没有尝试过。我尝试将“ $ colors”变量添加到我的variable.scss中，并使用“ color =” primary“”，但这没有用。这是我的代码，

html

<ion-tabs>
  <ion-tab label="Home" icon="home" href="/tabs/(home:home)">
    <ion-router-outlet name="home"></ion-router-outlet>
  </ion-tab>
  <ion-tab label="Passport" icon="information-circle" href="/tabs/(passport:passport)">
    <ion-router-outlet name="passport"></ion-router-outlet>
  </ion-tab>
  <ion-tab label="Tours" icon="contacts" href="/tabs/(tours:tours)">
    <ion-router-outlet name="tours"></ion-router-outlet>
  </ion-tab>
</ion-tabs>

您可以通过将CSS应用于.tabbar类直接更改背景

Public Module Mathematics
  Public Function Sum(x As Integer, y As Integer) As Integer
    Return x + y
  End Function
End Module

Class Form1
  Public Sub New()
    InitializeComponent()
    Dim result = Mathematics.Sum(1, 2)
  End Sub
End Class
