Help Edit Code to not show byline in post

Could someone please tell me the correct change to make on this code so that the (child) theme will not show the author or categories in the byline right under the post title. This is from the post.php file. Or the correct entry to put into my style.css?

<?php echo apply_atomic_shortcode( 'byline', '<div class="byline">' . __( '[entry-published] &middot; by [entry-author] &middot; in [entry-terms taxonomy="category" before=""] [entry-edit-link before=" &middot; "]', 'origin' ) . '</div>' ); ?>
