Overview
BlockGlow adds a “BlockGlow — Custom CSS” panel to the inspector of every block. Use it to scope custom CSS to a single block instance. The plugin stores CSS in the uploads folder (under uploads/blockglow/) and enqueues the generated CSS file when rendering on the front end. If the uploads directory isn’t writable or file write fails, BlockGlow will fall back to outputting inline styles.
Key features:
- Adds two block attributes to every block:
blockglowCustomCSSandblockglowId. - Inspector panel with a CodeMirror-backed code editor (if WordPress provides it) or a fallback textarea supporting Tab and Shift+Tab outdent.
- Live preview inside the block editor: custom CSS is scoped to the block in the editor so you can see the effect while editing.
- CSS files are saved to
wp-con…
