BLX — A lightweight collection of Webflow-friendly enhancements

BLX is a set of small, focused JavaScript packages designed to add useful behaviour to Webflow and similar no-code setups. Each package is self-contained, easy to integrate, and built with real-world Webflow constraints in mind.

The repository is structured so you can:

• load only the packages you use
• or load everything through a single global loader
• keep clean versioning through GitHub Releases + jsDelivr CDN
• scale the library as more packages are added

📚 At the moment, BLX includes:

• TOC (Table of Contents) package
• Inline SVG package
• Modal package
• Social Share package
• Copy to Clipboard package
• Mapbox package

🚀 Usage

Loading via jsDelivr CDN

All packages are available via jsDelivr CDN, which automatically minifies them when you use the .min.js extension. You can load them individually or all together.
