make entire column clickable in post slider

Hey pelgrimrat,

Thank you for the inquiry.

You can add this code in the functions.php file to make the excerpt clickable with the same link as the title and featured image.

function ava_custom_script_mod() {
    ?>
    <script>
    // make post grid excerpt clickable
    jQuery(document).ready(function($) {
        $('article.slide-entry').each(function() {
            const $article = $(this);
            const link = $article.find('a.slide-image').attr('href');

            if (link) {
                const $excerpt = $article.find('.slide-entry-excerpt');

                $excerpt.css('cursor', 'pointer').on('click', function(e) {
                    if (!$(e.target).closest('a').length) {
                        window.location.href = link;
                    }
                });
            }
        });
    });
    </script>
    <?php
}
add_action( 'wp_footer', 'ava_custom_script_mod', 9999 );

Let us know the result.

Best regards,
Ismael
