In this Pro tutorial we are going to prefilter the posts using a date query to those published today and conditionally output the Bricks Section having the Posts element/Query Loop only if there is at least 1 published post today.
Additionally, we shall programmatically add “s” at the end of “Today’s Article” if there is more than 1 post published today.

Add a Section having a Today's Article Heading and Posts element.

Add the following in child theme‘s functions.php (w/o the opening PHP tag) or a code snippets plugin:
// Function to get the count of number of posts published today.
function bl_get_today_post_count() {
$args = array(
'date_query' => array(
array(
'year' => date( 'Y' ),
'month' => date( 'm' ),
'day' => date( 'd' ),
),
),
);
$query = new WP_Query( $args );
return $query->found_posts;
}
// Prefilter posts to those published today.
add_filter( 'bricks/posts/query_vars', function( $query_vars, $settings, $element_id ) {
$date_query = array(
array(
'year' => date( 'Y' ),
'month' => date( 'm' ),
'day' => date( 'd' ),
)
);
if ( 'svjwaz' === $element_id ) {
$query_vars['date_query'] = $date_query;
}
return $query_vars;
}, 10, 3 );
// Add "s" at the end of a specific heading element's text if there is more than 1 post published today.
add_filter( 'bricks/element/settings', function( $settings, $element ) {
if ( $element->id === 'qjkndd' && bl_get_today_post_count() > 1 ) {
$settings['text'] .= 's';
}
return $settings;
}, 10, 3 );
Replace svjwaz with the Bricks ID of your Posts element or the Query Loop element.
Replace qjkndd with the Bricks ID of your Heading element.
