/wp-theme applies site-wide visual changes by editing your theme’s global styles, not individual pages.
What you can change
- Body, heading, and link colors
- Background and accent colors
- Typography (font family, base size, line height)
- Header and footer template parts
- Navigation menu order and labels
- Global CSS injected via theme.json or wp_head
Examples
- “Update my site theme — dark background (#0d0d1a), white headings, purple accent (#7c3aed).”
- “Change the body font to Inter and bump the base size to 17px.”
- “Add a Free Audit link to the main nav, second from the right, after Pricing.”
- “Make the footer text larger and white on this dark background — I can barely read it.”
How it ships
For modern block themes (Twenty Twenty-Three, Twenty Twenty-Four, Twenty Twenty-Five), Claude edits theme.json and the FSE global-styles record. For classic themes, Claude injects equivalent CSS via wp_head. Either way, the change is site-wide and immediate.
Reverting
“Revert the last theme change” — Claude has a snapshot of what it changed and can undo it. For larger rollbacks use /wp-restore.
