Meta box with front-end styling

You don’t need a checkbox, you can code one if you want, but you can use the default Custom Fields.

Make sure they are enabled:

Then add some data on the posts you want to have a specific style on, you will need to add this to each post you want to have set to display: none;:

Now inside the loop of your page you will add that value as a CSS class:

 // loop starts
 <?php $authoryes = get_post_meta( get_the_ID(), 'authordisplay', true ); ?>
 <div class="page<?php echo $authoryes; ?>">
 // rest of the loop
 </div>

So now you just have to add one style to your CSS for .pageauthor

You should probably use a more unique name than “author” for the value, I did this fast.
