Changing default comments class- help

Hi there!

ACF Support Team here, Thanks for reaching out with your query we would be happy to assist.

I am afraid ACF as it is out of the box doesn’t modify third party plugins.

ACF is a developer’s tool that lets you to quickly create custom fields and attach them to different items such as post types. Then one can add custom code to theme files to display custom fields’ data on the front as discussed at https://www.advancedcustomfields.com/resources/displaying-custom-field-values-in-your-theme/.

​It also has a REST API feature where a client can retrieve custom field data as discussed at https://www.advancedcustomfields.com/resources/wp-rest-api-integration/#developer-notes.

Please read more about ACF on our site at ​https://www.advancedcustomfields.com/.

​You can check out our documentation at https://www.advancedcustomfields.com/resources/.

​You can also have a look at third-party youtube tutorials such as https://www.youtube.com/watch?v=eMCOE9x5mCc&list=PLgFB6lmeXFOoyP8YUj7TmDnzFrrPcjCf3
