如何在wordpress中显示页面每个部分的不同数量的帖子

Question

I am trying to make a Wordpress theme which has a different number of posts in each section. Suppose the first section includes only one posts and as we scroll to the next section we more than one maybe 6 posts. The problem is I am not sure how to do that in WordPress. For the first post, I queried this way but it renders only one posts in each section.

I want to achieve this have a look on this website example

<?php
        if(have_posts()): ?> 
            <div class="row">
            <?php while(have_posts()): the_post(); ?>

                <?php get_template_part('template-parts/content', get_post_format());?>

            <?php endwhile;wp_reset_postdata(); ?>
            </div>

        <?php else: ?>


            <?php get_template_part('/template-parts/content', 'none');?>

        <?php endif
        ?>

Please help me to figure out this.
