  color: #808080;
  font-size: 14px;

}

Customization via Vue binding

Vue also allows developers to dynamically change placeholder text via data binding:

<input v-model="username" :placeholder="usernamePlaceholder">

export default {
  data() {
    return {
      usernamePlaceholder: 'Please enter your username'
    };
