How to create bootstrap grid loop?

Question

Okay I got it! And this code works perfectly for me. 🙂

<?php             $args=array(
                 'post_type' => 'post',
                  'posts_per_page' => 4,
                  'paged' => $paged,
                  'tax_query' => array(
                              array(                
                                  'taxonomy' => 'post_format',
                                  'field' => 'slug',
                                  'terms' => array('post-format-video'),
                                  'operator' => 'IN')
                                  )
                );

              $my_query = null;
              $my_query = new WP_Query($args);

              if( $my_query->have_posts() ) {

                $i = 0;
                while ($my_query->have_posts()) : $my_query->the_post();
              // modified to work with 3 columns
              // output an open <div>
              if($i % 4 == 0) { ?> 

              <div class="row">

              <?php
              }
              ?>

                <?php get_template_part( 'template/loop', 'video' ); ?>
                  <?php $i++; 
                  if($i != 0 && $i % 4 == 0) { ?>
                    </div><!--/.row-->
                    <div class="clearfix"></div>

                  <?php
                   } ?>

              <?php endwhile; } wp_reset_query();?>
