Dear @Ajay S

Try to replace your register.component.html with:

<section class="view intro intro-2">
  <div class="full-bg-img mask rgba-gradient rgba-indigo-slight">
    <div class="container py-5">
      <!--Grid row-->
      <div class="row  pt-5 mt-3">
        <!--Grid column-->
        <div class="col-md-12">
          <mdb-card>
            ...
          </mdb-card>
        </div>
      </div>
    </div>
  </div>
</section>

and add to your styles.scss :

.view {
  .mask {
    overflow-y: scroll;
  }
}

Best Regards, Bartosz.
