html - Jekyll every 4th item in loop display differently -


i using jekyll populate blog page blog posts. want there 2 posts every div "row" class, want every 4th item ad (skip on post , move next row still include else that's not post).

so if there 6 posts, output should this

<div class="row"> <!-- 1st row -->   <div> {{ post.title }} </div>  <!-- 1st post, no skip -->   <div> {{ post.title }} </div>  <!-- 2nd post, no skip --> </div>  <div class="row"> <!-- 2nd row -->   <div> {{ post.title }} </div>  <!-- 3rd post, no skip -->   <div> not post </div>  <!-- skip post 4, put else --> </div>  <div class="row"> <!-- 3rd row -->   <div> {{ post.title }} </div>  <!-- 4th post, because last item skipped display else -->   <div> {{ post.title }} </div>  <!-- 5th post, no skip --> </div>  <div class="row"> <!-- 4th row -->   <div> {{ post.title }} </div>  <!-- 6th post, no  skip --> </div>  <!-- , on, every 4th item not post, posts continue after skipped post -->

i have post loop part cant figure out how add skip

{% assign rows = site.posts.size | divided_by: 2.0 | ceil %} {% in (1..rows) %}   {% assign offset = forloop.index0 | times: 2 %}   <div class="row blogitems">     {% post in site.posts limit:2 offset:offset %}         <div class="col-md-6">           <p>{{ post.title }}</p>         </div>     {% endfor %}   </div> {% endfor %}

i think can walk through items while checking modulo. this:

<div class="row blogitems"> {% post in site.posts %}   {% assign mod3 = forloop.index | modulo: 3 %}   <div class="col-md-6"><p>{{ post.title }}</p></div>   {% if mod3 == 0 %}<div class="col-md-6"><p>this not post</p>{% endif %}   {% if mod3 == 0 or mod3 == 2 %}</div><div class="row blogitems">{% endif %} {% endfor %} </div>
