How come I am experiencing difficulty modifying the background color of ion-header using a CSS class selector within my Ionic Vue component?

Recently, I began my journey with ionic vue and started incorporating CSS with the components. I added styles in the same file like this:

<style scoped>
    .abc {
        background-color: blue;
    }
</style>

I attempted to apply these styles by using the following code:

<ion-content class ="abc">
    <ion-header>
        <ion-toolbar>
            <ion-title size="large">My Navigation Bar</ion-title>
        </ion-toolbar>
    </ion-header>
</ion-content>

Unfortunately, it didn't work as expected. How can I resolve this issue? Here is my complete code:

<template>
  <ion-page>
    <ion-content class ="abc">
        <ion-header>
          <ion-toolbar>
            <ion-title size="large">My Navigation Bar</ion-title>
          </ion-toolbar>
        </ion-header>
    </ion-content>
  </ion-page>
</template>

<script>
    import { IonContent, IonPage } from "@ionic/vue";
    import { defineComponent } from "vue";

    export default defineComponent({
        name: "Home",
        components: {
            IonContent,
            IonPage
        },
    });
</script>

<style scoped>
    .abc {
        background-color: blue;
    }
</style>

Answer №1

I needed to make some adjustments to the code below

<style scoped>
    .xyz {
        --background: red;
    }
</style>

and then choose the css class from the toolbar

<ion-toolbar class="xyz">
