Create FirstComponent.vue and import it into App.js

Create the new component in the src/components/ components folder. the component name is FirstComponent.vue and imported into the App.js file:

App.js

<template>
  <div id="app">
    <FirstComponent />
  </div>
</template>

<script>
import FirstComponent from "./components/FirstComponent.vue";
export default {
  name: "App",
  components: {
    FirstComponent,
  },
};
</script>

<style>
#app {
  font-family: Avenir, Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
  margin-top: 60px;
}

Apply classes to the active tab

For adding a basic tab with content we are using the BootstrapVue <b-tab> component. If we want to apply classes to the currently active control or tab then we have to use the active-nav-item-class and active-tab-class props. Let’s see the code example:

FirstComponent.js

<template>
  <b-container fluid>
    <b-row>
      <b-col md="6" offset-md="3">
        <h1>Welcome to sortoutcode.com</h1>
        <b-tabs active-nav-item-class="text-uppercase text-success"
          active-tab-class="text-danger" content-class="mt-3">
          <b-tab title="First">
            <p>Hello everyone, This is the first tab</p>
          </b-tab>
          <b-tab title="Second">
            <p>Hello everyone, This is the Second tab</p>
          </b-tab>
          <b-tab title="third">
            <p>Hello everyone, This is the third tab</p>
          </b-tab>
        </b-tabs>
      </b-col>
    </b-row>
  </b-container>
</template>
<script>
export default {
  name: "FirstComponent",
};
</script>

For now, let’s check the output.

All the best 👍.
