Why use a child theme for Twenty Twenty-One?
Every time Twenty Twenty-One ships an update, any direct edits you made to its files are overwritten. A child theme isolates your changes — custom CSS, template overrides, additional functions — so the parent can update freely while your customizations stay intact.
- ✓Survive Twenty Twenty-One updates without losing your edits.
- ✓Override any Twenty Twenty-One template file by copying it into the child.
- ✓Add custom hooks, shortcodes, or enqueue your own scripts.
- ✓Roll back to the parent at any time by deactivating the child.

Generate Twenty Twenty-One Child ThemeFrequently asked questions
What is a Twenty Twenty-One child theme? +
A child theme is a separate WordPress theme that inherits all functionality, design, and templates from Twenty Twenty-One (its parent). You make your customizations in the child so they survive updates to the parent theme.
Do I need to know code to use this generator? +
No. The generator creates a complete, valid Twenty Twenty-One child theme with style.css, functions.php, screenshot.png, and README.txt. You can customize via the form fields, and if you want to add custom CSS or PHP later you can edit the files directly.
Will the child theme break when Twenty Twenty-One updates? +
That's exactly what a child theme is designed to prevent. Twenty Twenty-One can be updated freely without losing your customizations, because they live in the child theme files.
Is this generator really free? +
Yes. There is no signup, no payment, and no limit on how many Twenty Twenty-One child themes you can generate. The zip is built on demand and downloaded directly to you.
