Create Block Theme

This plugin allows you to:

• Create a blank theme
• Create a new theme based on the currently active theme
• Create a child theme of the active parent theme
• Create a new style variation
• Export a theme
• Save user changed templates and styles to the active theme

All newly created themes or style variations will include changes made within the WordPress Editor.

This plugin also makes several changes to the contents of a theme, including:

• Adds all images used in templates to the theme’s assets folder.
• Ensures the block markup used in templates and patterns is export-ready.
• Ensures most strings used in templates and patterns are translate-ready.

The plugin is development only — not intended for use on production websites, but used as a tool to create new themes.

Step 1 – Setup

Install and activate the Create Block Theme plugin.

There will be a new panel accessible from the WordPress Editor, which you can open by clicking on a new icon to the right of the “Save” button, at the top of the Editor.

Step 2 – Style Customizations

Make changes to your site styles, fonts and templates using the Editor.

Step 3 – Export

Still in the WordPress Editor, navigate to the Create Block Theme menu at the top of the Editor.

To install and uninstall fonts:

• Install and activate a font from any source using the WordPress Font Library.
• Select “Save Changes To Theme” and select “Save Fonts” to save all of the active fonts to the currently active theme. These fonts will then be activated in the theme and deactivated in the system (and may be safely deleted from the system).
• Any fonts that are installed in the theme that have been deactivated with the WordPress Font Library will be removed from the theme.

or export the theme:

• Select “Export Zip” to export the theme as a zip file.

To edit the theme metadata:

To create a new Clone of the current theme or to create a Child of the current theme:ons for the currently active theme:

Many of these options are also available under the older, deprecated Create Block Theme page under Appearance > Create Block Theme.
