How To Remove The Author(s) From Certain Posts

There are certain posts on the website I’m developing, that don’t need the author(s) by-line. (such as press releases)

Is there any method, that allows me to remove the author (and co-authors) for certain posts?

A quick fix would be to use WP’s body class and in your stylesheet target the element containing the autor name to hide it for the page(s) you want.

For example :

.page-id-227 #my_authors{ display: none }

Update :

Another solution would be to use conditional tags in your templates, to print the author names only on wanted pages.
