I have built out the below page in wordpress, single.php, with a custom slider on the top. Currently the slider is showing the posts from all categories with the post body showing the correct content.
What I need is 3 pages, single1.php, single2.php, and single3.php showing only the posts from category 1 on single1.php, category 2 on single2.php, and category 3 on single3.php.
<div class="row">
<div class="col-md-12 col-xs-12">
<div id="primary" class="content-area">
<main id="main" class="site-main" role="main">
<div class="cap-cont">
<div class="cap">CHOOSE A AUTHOR</div>
<div class="auth-slide">
<?php
$loop = new WP_Query( array( 'post_type' => 'post', 'posts_per_page' => 30, 'post_status' => 'publish', 'orderby' => 'rand' ) );
while ( $loop->have_posts() ) : $loop->the_post();
$content .= '<div><a href="';
$content .= get_permalink();
$content .= '">';
$content .= get_the_post_thumbnail();
$content .= '</a></div>';
endwhile;
echo $content;
?>
</div>
</div>
