           {% endprevArchive %}
       </div>
   
       <div class="next-archive text-end">
           {% nextArchive next %}
               {% if next %}
                   <a href="{{next.Link}}" title="{{next.Title}}" class="d-flex align-items-center justify-content-end">
                       <div>
                           <small>下一篇</small>
                           <div class="title-ellipsis">{{next.Title}}</div>
                       </div>
                       {% if next.Thumb %}
                           <img src="{{next.Thumb}}" alt="{{next.Title}}" class="thumbnail ms-2">
                       {% endif %}
                   </a>
               {% else %}
                   <span class="text-muted">没有下一篇了</span>
               {% endif %}
           {% endnextArchive %}
       </div>
   </div>
   

   In this example, we added simple CSS classes liked-flex,justify-content-between,align-items-center,me-2,ms-2,text-end,title-ellipsisSimulate a navigation style aligned to the left with thumbnails and title truncation.
