django/bootstrap/infinity scroll(https://infinite-scroll.com)

I want to add infinity scroll to my news page. Queryset with 2 types of news, big(col-lg-8) and small(col-lg-4). Now I have problems with blocks (see example picture). How to make pagination page added to the previous page row?

Example

 <div class="container">
 <div class="article-feed">
     <div class="row iscroll">
    {% for art in all %}
     {% if art.banner_page %}
<div class="col-lg-8 mb-2 mt-2">
<img class="card-img-top" src="{{art.banner.url}}" >
</div>
   {% else %}
 div class="col-lg-4 mb-2 mt-2 ">
 <img class="card-img-top" src="{{art.banner.url}}" >
 </div>

         {% endif %}{% endfor %}



 <p class="pagination">
 <a class="pagination__next" href="?page={{ page_obj.next_page_number }}">
 </a></p>



 <script src="{% static "js/infinite-scroll.pkgd.min.js" %}"></script>
   <script>
 $('.article-feed').infiniteScroll({
   path: '.pagination__next',
   append: '.iscroll',
 });
   </script>
