Enabling all appearance tools in your block theme is surprisingly simple – just one setting in your theme.json file does the trick.
Add a “settings” section to your theme.json (if you don’t have one already), then include “appearanceTools: true” within that settings object. Make sure to follow proper JSON syntax with commas and valid formatting.
Save the file and reload your site editor to see the change. You’ll immediately notice additional customization options appearing in the block sidebar – dimensions, borders, advanced spacing controls, and more.
This single setting unlocks the full potential of WordPress’s built-in design system, giving you access to every customization tool without the tedious work of enabling each feature individually.
