Block themes let you design headers, footers, templates and global styles without editing code.
Steps
- Take a backup, then open Appearance → Themes → Add New and filter for block themes.
- Preview and activate the chosen theme in staging first.
- Open Appearance → Editor. Set global colors, typography and layout under Styles.
- Edit Navigation, Header and Footer template parts; use List View to understand nested blocks.
- Build pages with patterns, check mobile/tablet previews and save only the intended template changes.
Verify the result
Test navigation, contrast, forms, keyboard use and several screen sizes; export the theme changes when available.
Important: Changing themes can hide old widgets or menus. Keep the previous theme installed until the new design is verified.
