Load more in news feed

Button with id="load-more-button" is responsible for adding content to a page. The button itself has the following look: 

<a id="load-more-button" href="#" class="btn btn-control btn-more" data-load-link="items-to-load.html" data-container="newsfeed-items-grid">
 <svg class="olymp-three-dots-icon">
  <use xlink:href="icons/icons.svg#olymp-three-dots-icon"></use>
 </svg>
</a>
It includes the following data-attributes:
data-load-link="items-to-load.html" – where you need to specify the path to the HTML page with content to display;
data-container="newsfeed-items-grid" — where you need to specify the class of the block (div), where the content will be added.
