I’m trying to use Formly for angular and primeng for the first time

https://v5.formly.dev/

But the example they provide looks bad:

This is the example as they provide it:

How do I properly align that? The page doesn’t explain it…

<div class="header">
    <img src="https://raw.githubusercontent.com/ngx-formly/ngx-formly/v5/logo.svg?sanitize=true" alt="" width="72" height="72">
    <h4 class="mat-h2">Angular Formly PrimeNg</h4>
  </div>
  <form [formGroup]="form" (ngSubmit)="onSubmit()">
    <formly-form
      [form]="form"
      [model]="model"
      [fields]="fields">
    </formly-form>

    <div>
      <button pButton type="submit" label="Submit"></button>
      <button pButton type="reset" label="Reset" class="ui-button-danger"></button>
    </div>
  </form>

Component:

import { Component } from '@angular/core';
import { FormGroup } from '@angular/forms';
import { FormlyFieldConfig } from '@ngx-formly/core';

@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
})
export class AppComponent {
  form = new FormGroup({});
  model = {};
  fields: FormlyFieldConfig[] = [
    {
      key: 'input',
      type: 'input',
      templateOptions: {
        label: 'Input',
        placeholder: 'Input placeholder',
        required: true,
      },
    },
    {
      key: 'textarea',
      type: 'textarea',
      templateOptions: {
        label: 'Textarea',
        placeholder: 'Textarea placeholder',
        required: true,
      },
    },
    {
      key: 'checkbox',
      type: 'checkbox',
      templateOptions: {
        label: 'Checkbox',
      },
    },
    {
      key: 'select',
      type: 'select',
      templateOptions: {
        label: 'Select',
        placeholder: 'Select placeholder',
        required: true,
        options: [
          { label: 'Option 1', value: '1' },
          { label: 'Option 2', value: '2' },
          { label: 'Option 3', value: '3' },
        ],
      },
    },
    {
      key: 'radio',
      type: 'radio',
      templateOptions: {
        label: 'Radio',
        required: true,
        options: [
          { label: 'Option 1', value: '1' },
          { label: 'Option 2', value: '2' },
        ],
      },
    },
  ];

  onSubmit() {
    if (this.form.valid) {
      alert(JSON.stringify(this.model, null, 2));
    }
  }
}
