Question: Instead of each post going into it's own <li>, what if I wanted three posts per <li> element? Answer: loop

wp-loop.php

<ul class="slides">
        <li>
                <?php 
                $count  = 0;
                query_posts('post_type=testimonials&posts_per_page=-1'); if ( have_posts() ) while ( have_posts() ) : the_post(); ?>
                                <h3>
                                        <?php the_post_thumbnail(); ?>
                                        <?php the_title();?>
                                        <span><?php the_field('job_position'); ?></span>
                                </h3>
                                <?php the_content();?>
                                <span class="website">View website in action: <a title="View <?php the_field('website_name'); ?>" href="<?php the_field('website_link'); ?>"><?php the_field('website_name'); ?></a></span>
                                // Every 3rd loop, reset the li.
                        <?php  if ($count == 2){ ?></li>
                                <?php if(get_next_post() != ''){ ?><li><?php } ?>
                        <?php $count  = 0; }else {$count++;} ?>
                <?php endwhile; wp_reset_query(); ?>
        </li>
</ul>
