🚀 Launching style-observer: A bulletproof, production-ready library for observing CSS property changes in JS.

Developed with the help of my apprentice @dmitrysharabin over the last month, to scratch possibly one of my longest-standing itches.

Made possible by the pioneering work of @bramus, Artem Godin, @JaneOri and many others!
