Start by disabling WordPress default font sizes in theme.json by setting “defaultFontSizes: false” under typography settings. This clears the slate for your custom palette.
Use the site editor’s font size presets interface (available in WordPress 6.7+) to create your first size. Name it “Small” and set the value using rem units for better accessibility and scalability.
For fluid typography, WordPress can automatically generate minimum and maximum values from your base size. Export your changes using Create Block Theme to move the definitions from database to theme files.
Complete your palette by duplicating and modifying the theme.json entries, or continue using the interface for each size. The result is a clean, professional typography system that matches Bosco’s original design.
