related.php Styling CSS/Javascript

I am trying to override the Classes and ID’s and also some javascript in the “Related Products” section of single product pages. I want to replace the current styling with this nice looking one (http://nicesnippets.com/live/best-product-display-slider-using-bootstrap-demo.html).

But I am unable to locate the html to change the classes.

I would really appreciate any help or guidance.

This is the code I am using:

<?php
/**
 * Related Products
 *
 * This template can be overridden by copying it to yourtheme/woocommerce/single-product/related.php.
 *
 * HOWEVER, on occasion WooCommerce will need to update template files and you
 * (the theme developer) will need to copy the new files to your theme to
 * maintain compatibility. We try to do this as little as possible, but it does
 * happen. When this occurs the version of the template file will be bumped and
 * the readme will list any important changes.
 *
 * @see 	    https://docs.woocommerce.com/document/template-structure/
 * @author 		WooThemes
 * @package 	WooCommerce/Templates
 * @version     3.0.0
 */

if ( ! defined( 'ABSPATH' ) ) {
	exit;
}

global $product, $woocommerce_loop;

if ( empty( $product ) || ! $product->exists() ) {
	return;
}

if ( ! $related = $product->get_related( $posts_per_page ) ) {
	return;
}

$args = apply_filters( 'woocommerce_related_products_args', array(
	'post_type'            => 'product',
	'ignore_sticky_posts'  => 1,
	'no_found_rows'        => 1,
	'posts_per_page'       => $posts_per_page,
	'orderby'              => $orderby,
	'post__in'             => $related,
	'post__not_in'         => array( $product->id )
) );

$products                    = new WP_Query( $args );
$woocommerce_loop['name']    = 'related';
$woocommerce_loop['columns'] = apply_filters( 'woocommerce_related_products_columns', $columns );

if ( $products->have_posts() ) : ?>

<div class="collection-products">
            <?php woocommerce_product_loop_start(); ?>

            <?php while ( $products->have_posts() ) : $products->the_post(); ?>

                    <?php wc_get_template_part( 'content', 'product' ); ?>

            <?php endwhile; // end of the loop. ?>

            <?php woocommerce_product_loop_end(); ?>

	</div>

<?php endif;

wp_reset_postdata();
