Overview

The missing inline block CSS editor for the Gutenberg editor. Very powerful with synced patterns as well. And it pairs well with global styles.

This plugin is perfect for users looking to add CSS for blocks without needing to create a child theme, or use a bloated plugin. Client safe too. CSS won’t leak outside of the block, and only valid block CSS is persisted.
