Hide field if there is no field content to show - BUT - also how to output content with specific html in it.
<!-- in this example, the fucntion checks the acf field to see if there is content. If there is no content, the field is hidden. If there is content (# of credit hours here) the numbers are printed to screen with the word 'credits' and a pair of () --> <?php if( get_sub_field('number_of_credits') ): ?> <span class="new-line-xs">(<?php the_sub_field('number_of_credits'); ?> credits)</span> <?php endif; ?> <!-- Note the () wrapped around the function "the_sub_field('number_of_credits');" along with the word "credits". -->
