An interesting – albeit flawed – attempt at a zero-dependencies, web standards focused, PWA based UI framework, and a potentially useful quick-start template for using web components and native APIs to build a lightweight web app. I will caution that the author has some odd ideas about both HTML and front end development in general. For example: they advocate the use of <label> wrappers for <input>, but fail to understand that you still need the id attribute for accessibility purposes. They also chose to use a range slider as the basis for a switch component 🤷‍♀️ So, I like the underlying principles and general idea, but wouldn't recommend using this as-is or copying code verbatim; it's definitely not reliable, and as the author doesn't even have their own personal website, it's hard to know how experienced they are in actual front end development.
