my-winder

my-winder is a zero-dependency, runtime CSS-in-JS library that applies utility-first styles directly via inline `element.style` properties, eliminating the need for a build step or stylesheet generation. Version 1.1.7 is the current stable release, with no active maintenance cadence documented. Unlike Tailwind or other utility-first frameworks, my-winder operates entirely at runtime with no build step, using a `my-` prefixed class convention to map to CSS properties. It supports automatic MutationObserver-based re-scanning for dynamically added classes. Key differentiators: no build tooling, zero dependencies, works in browser and with shadow DOM, and supports CDN usage via esm.sh.
