It’s pretty but it could be so much more stunning.

It’s like having a template for all your content but instead of a single template it’s more like a flexible blueprint.
How theme.json Connects with the Block Editor
Think of theme.json as the brain behind the Block Editor.
It allows you to do things like:
- Control the editor programmatically: You can dictate what features show up in the editor making it more user-friendly for yourself and anyone else working on the site.
- Integrate a block style system: This lets you manage all the different styles for individual blocks making sure they all work together nicely.
- Set preferences for users: You can control whether users can make certain changes or access specific styles ensuring everyone stays on the same page (or rather same style!).
The Rise of the Site Editor
The Site Editor which is like the “global control panel” for your site’s design came along around the same time as theme.json.
They work hand-in-hand.
Think of the Site Editor as the gardener and theme.json as their toolbox.
The Site Editor is for big overarching changes like the general look of your website while theme.json lets you fine-tune the details.
