Hey there! If you’re tinkering with WordPress and have a knack for making sites look just right, you might like what we’ve cooked up with Core Framework. It’s like a Swiss Army knife for your CSS woes but way easier to use and with a lot more fun involved.
✅ Make It Yours: Ever felt boxed in by CSS frameworks? We get it. That’s why we made Core Framework as customizable as a build-your-own pizza.

Invaluable for any WordPress site without a page builder.
I have used ACSS and other Frameworks. I love Core as it is intuitive, lightm it has the right ammount of features for me, and you can easily remove the builder plugin (if you choose to use one) by simply exporting the styles and importing them directly into your builder. No lock-in. Support is great too. Thanks guys!

At some point it would be nice to be able to limit access to specific user roles.
This is awesome! 🤩 Thanks for making it freely available for Gutenberg. 🙏
It’s amazingly easy to manage classes and create custom style variation for items.
I love that it’s class-based and I can edit the class and it applies to the entire website, unlike other editors where appearance and style settings are tied to the element and can’t be edited globally.
