HI there,
You will have to install and enable the child theme for this and add this code in the functions.php file of the child theme:
// Entry Cover
// =============================================================================
if ( ! function_exists( 'x_ethos_entry_cover' ) ) :
function x_ethos_entry_cover( $location ) {
if ( $location == 'main-content' ) { ?>
<article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
<a class="entry-cover" href="<?php the_permalink(); ?>" style="<?php echo x_ethos_entry_cover_background_image_style(); ?>">
<h2 class="h-entry-cover"><span><?php x_the_alternate_title(); ?></span></h2>
</a>
</article>
<?php } elseif ( $location == 'post-carousel' ) { ?>
<?php GLOBAL $post_carousel_entry_id; ?>
<article <?php post_class(); ?>>
<a class="entry-cover" href="<?php the_permalink(); ?>" style="<?php echo x_ethos_entry_cover_background_image_style(); ?>">
<h2 class="h-entry-cover"><span><?php ( $post_carousel_entry_id == get_the_ID() ) ? the_title() : x_the_alternate_title(); ?></span></h2>
<div class="x-post-carousel-meta">
<span class="entry-cover-author"><?php echo get_the_author(); ?></span>
<span class="entry-cover-categories"><?php echo x_ethos_post_categories(); ?></span>
<span class="entry-cover-date"><?php echo get_the_date( 'F j, Y' ); ?></span>
<!-- Add the hover contents here -->
</div>
</a>
</article>
<?php }
}
endif;
Hope this helps.
