Generate your own Full Site Editing (FSE) child theme from existing themes.
Select a theme from the drop down list then choose the Preview button.
The page will be redisplayed with the selected theme’s style.
When you’ve found a style you like, choose the Parent theme upon which your new theme’s
template parts and
patterns will be found. If you’ve already selected a child theme then this will have been preselected.
The tool allows you to chose a Parent theme which is different from the Theme style, but your child theme may not work as expected.
Also choose settings for the Content size, Wide size, and Block gap, and enter your Child theme name.
Then choose the Download zip button.
If everything checks out a new child theme will be generated using
theme.json from the Theme style and setting the
template to the parent theme.
Download the .zip file and install it in your website. The parent theme should be installed automatically.
What you’ll get
The generated child theme will consist of a .zip file containing the child theme’s files.
|The mandatory file that identifies your new child theme and the required parent theme (
This file won’t contain any CSS, even if the theme you selected did have some.
You may wish to edit this file to set your own values.
|A copy of the
theme.json file from the original theme, which itself may have been a child theme, with adjustments made for the settings you chose.
|The readme file for the generated theme.
