About Heckl

A block theme for personal feed readers and social-style content sites, with layouts tuned for photo grids, vertical video, and text timelines. Works on its own and pairs with the Heckl Tools plugin, which adds Following, Favorites, and a frontend post composer.

Why use a child theme for Heckl?

Every time Heckl 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 Heckl updates without losing your edits.
  • Override any Heckl 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 Heckl child theme

  1. 1

    Configure and generate

    Open the generator (already pre-filled with Heckl as the parent), enter your child theme name and any custom CSS.

  2. 2

    Download the ZIP

    The generator builds a ready-to-install ZIP containing style.css, functions.php, screenshot.png and README.txt.

  3. 3

    Upload to WordPress

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

Frequently asked questions

What is a Heckl child theme? +

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

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