How do i change this so after the first three posts it stops the loop and returns with the rest of the posts in a separate row
<?php
$the_query = new WP_Query( 'posts_per_page=3' );
?>
<?php
while ($the_query -> have_posts()) : $the_query -> the_post();
?>
<div class="col-md-4">
<a href="<?php the_permalink() ?>">
<?php the_title(); ?>
</a>
<?php the_excerpt(__('(more…)')); ?>
</div>
<?php
endwhile;
wp_reset_postdata();
?>
posts_per_page=3 will only return 3 posts, so you'll have to change that value to the number of posts (in your case excerpts) you want to display on that page.
