<?php get_header(); ?>


<h1><?php single_cat_title(); ?></h1>


<?php
if ( have_posts() ) {
    $i = 0;
       while ( have_posts() ) {
            $i++;
            if ( $i > 1 ) {
                echo '<hr class="post-separator styled-separator is-style-wide section-inner" aria-hidden="true" />';
            }
            the_post();
            get_template_part( 'template-parts/content', get_post_type() );
        }
}
?>


<?php get_footer(); ?>
