About Hassium
A block theme for software companies and startups, built on the Core Forms design system. Hassium is element 108, first made in a lab in Darmstadt a few atoms at a time, and the theme is for small teams who build that way. It pairs Inter with Hedvig Letters Serif headings, puts one brand color on everything that asks to be clicked, and ships a frosted sticky header, dark and brand bands, screenshot frames, pricing tables, changelogs, and complete landing pages. Includes 67 patterns, six designs, three heading presets, core blocks only, and no JavaScript of its own.

Why use a child theme for Hassium?
Every time Hassium 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 Hassium updates without losing your edits.
- ✓Override any Hassium 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 Hassium Child ThemeFrequently asked questions
What is a Hassium child theme? +
A child theme is a separate WordPress theme that inherits all functionality, design, and templates from Hassium (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 Hassium 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 Hassium updates? +
That's exactly what a child theme is designed to prevent. Hassium 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 Hassium child themes you can generate. The zip is built on demand and downloaded directly to you.
