Why use a child theme for Newstack?

Every time Newstack 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 Newstack updates without losing your edits.
  • Override any Newstack 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.

    In WordPress: Appearance → Themes → Add New → Upload Theme. Choose the ZIP, click Install Now, then Activate. Make sure Newstack itself is also installed (the parent must be present).

Frequently asked questions

What is a Newstack child theme? +

A child theme is a separate WordPress theme that inherits all functionality, design, and templates from Newstack (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 Newstack 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 Newstack updates? +

That's exactly what a child theme is designed to prevent. Newstack 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 Newstack child themes you can generate. The zip is built on demand and downloaded directly to you.
