I have just added a draft section to the Theme Review Guidelines, to cover requirements for Child Theme support/facilitation for hosted Themes:
- Themes are required to facilitate the use of Child Themes. A “basic” Child Theme A Child Theme is a customized theme based upon a Parent Theme. It’s considered best practice to create a child theme if you want to modify the CSS of your theme. https://developer.wordpress.org/themes/advanced-topics/child-themes/. (i.e. a style.css with Template header The header of your site is typically the first thing people will experience. The masthead or header art located across the top of your page is part of the look and feel of your website. It can influence a visitor’s opinion about your content and you/ your organization’s brand. It may also look different on different screen sizes. tag and @import() of the Template style.css), when activated, should function exactly as the Theme itself functions.
- Themes are required to include functional and resource files in a manner that facilitates the use of Child Themes:
Based on discussion on the mail-list, consensus appears to be that facilitating end user use of Child Themes is beneficial, so this discussion is the first step in incorporating Child Theme support into the Guidelines.
Please discuss. Do you agree/disagree that Child Theme support should be added to the Guidelines? Are the above Guidelines sufficient? What should be added/removed/changed? What about pluggable/filterable functions?
Child-Themes will now be considered for inclusion into the WordPress Extend Themes repository.
Please be sure to read the Theme Review process and guidelines; also, please note the additional Child-Theme guidelines before submitting a Child-Theme for consideration.
Please note, although at the time of this writing the upload script may note the Child-Theme “fails” as the criteria used for Child-Themes is slightly different. If the Child-Theme did actually pass you would see at the bottom of the upload acknowledgement page a reference to the new Themes Trac Trac is the place where contributors create issues for bugs or feature requests much like GitHub.https://core.trac.wordpress.org/. ticket as well as receiving an email referencing the ticket as well.
You will also be able to check the open status of the Child-Theme in this Trac report: https://themes.trac.wordpress.org/report/6
I thought we already allowed child themes for BuddyPress as an exception to the rule?
This ticket https://themes.trac.wordpress.org/ticket/2996 was an update for https://wordpress.org/extend/themes/buddypress-widget-theme and was just rejected for being a child theme – I would have re-opened the trac ticket and commented there but I don’t have the rights to do that on the Theme Review trac.
