Every block has a unique identifier - 'class' or 'id'.
Plugin template files can be found in the following directory
/wp-content/plugins/gallery-plugin/templates/ (pro: /wp-content/plugins/gallery-pro-plugin/templates/).
You can edit these files in an upgrade-safe way using overrides. Copy them into a directory with your theme named
Example: To change the single gallery template, copy
PRO:copy /wp-content/plugins/gallery-pro-plugin/templates/gallery-pro-single-template.php to wp-content/themes/your-theme/bws-templates/gallery-pro-single-template.php
You can use the same classes or ID's for these elements, or add HTML elements and change the page structure.
Note: Do not edit these files in the plugin’s core directly as they are overwritten during the upgrade process and any customizations will be lost.
