Change the label text size with the form group component

Using the <b-form-group> component we are adding some structure to the form. Its purpose is to add the form control with a label and to provide help text and invalid/valid feedback text, as well as visual (color) contextual state feedback.

We can change the label text size which matches the size of your form input(s). For that, we are going to use the label-size props. Values can be sm or lg for the small or large labels, respectively. Sizes work for both horizontal and non-horizontal form groups. 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-form-group label="Sitename with label small size" label-size="sm">
          <b-form-input v-model="sitename"></b-form-input>
        </b-form-group>
        <b-form-group label="Sitename with label medium size" label-size="md">
          <b-form-input v-model="sitename"></b-form-input>
        </b-form-group>
        <b-form-group label="Sitename with label large size" label-size="lg">
          <b-form-input v-model="sitename"></b-form-input>
        </b-form-group>
      </b-col>
    </b-row>
  </b-container>
</template>
<script>
export default {
  name: "FirstComponent",
  data() {
    return {
      sitename: '',
    }
  },
};
</script>

For now, let’s check the output.
