Customize component

The Customize component covers all aspects of the Customizer, WordPress’ framework for live-previewing any change to your site. Tickets in this component cover issues including bugs in the Customizer (wp-admin/customize.php), PHP and JS API improvements, UI/UX changes, new features, and improvements to the Customizer internals. For more information about the Customizer API, please see its official documentation in the Theme Developer Handbook.

The Customizer is actively developed, with work happening on core trac, various GitHub repos, and in the #core-customize channel on WordPress Slack. Weekly meetings for the 4.7 cycle are held on Mondays at 17:00UTC.New contributors are always welcome, whether you bring code, design help, testing, or anything else. Below is a summary of our larger projects past and future projects, which were all accompanied by countless smaller changes.
