Why use a child theme for Altr?

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

How to install your Altr child theme

  1. 1

  2. 2

    Download the ZIP

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

Frequently asked questions

What is a Altr child theme? +

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

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