<div id="myCarousel2" class="carousel slide" data-ride="myCarousel2" data-interval="6000">
    <div class="carousel-inner-two" role="listbox">
    <!-- Start Bootstrap slider here  -->
        <!-- count for data-slide-to etc -->
        <?php $count = 0;?>

        <!-- custom args for page -->
        <?php $args = array('post_type' => 'slider', 'category_name' => 'home'); ?>
        <?php $query = new WP_query($args); ?>

        <?php if( $query->have_posts() ): while ( $query->have_posts() ) : $query->the_post(); //starts loop through top level repeater field for loop ?>

        <!-- adds textured images that is uploaded on the backend as full width background image -->
        <div class="item <?php if ( $count == 0 ) echo 'active'; ?>" style="background: url(<?php the_field('background');?>) no-repeat center / 100% auto;">

            <!-- Displays clickable CTA's on the banner -->
            <div class="max-width banner__content">
                <h2 style="margin-bottom: 0;"><?php the_title(); ?></h2>
                <?php the_content();?>
            </div>

        </div>

        <?php $count++; ?>
        <?php endwhile; else: ?>

            <p>No information available</p>
        <?php endif;?>
