Dismissing

  <button type="button" class="nj-close nj-alert__close" aria-label="Close">
    <span aria-hidden="true" class="material-icons nj-alert__close-icon">close</span>
  </button>
  <span aria-hidden="true" class="material-icons nj-alert__icon">notification_important</span>
  <div><span class="nj-alert__title">Notification</span>Lorem ipsum dolor sit amet, consectetur
    adipisicing elit
    asperiores. Lorem ipsum dolor sit amet, consectetur adipisicing elit.
  </div>
</div>
