About Osmium
A content-first block theme for writers, publishers, and review sites. Osmium puts the design in theme.json and the layout in patterns, so it ships no JavaScript of its own and stays out of the way of your words. Includes 22 templates, 138 patterns with a full review kit and pages from four sample sites, and six designs that restyle every one of them.

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