About BlankSlate

Donate: https://opencollective.com/blankslate. Learn: https://blankslate.me/. BlankSlate is the definitive WordPress boilerplate starter theme. I've carefully constructed the most clean and minimalist theme possible for designers and developers to use as a base to build websites for clients or to build completely custom themes from scratch. Clean, simple, unstyled, semi-minified, unformatted, and valid code, SEO-friendly, jQuery-enabled, no programmer comments, standardized and as white label as possible, and most importantly, the CSS is reset for cross-browser-compatability, with no intrusive visual CSS styles added whatsoever. A perfect skeleton theme. For support and suggestions, go to: https://github.com/webguyio/blankslate/issues. Thank you.

Why use a child theme for BlankSlate?

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

Frequently asked questions

What is a BlankSlate child theme? +

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

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