Show HN: StayedCSS – A CSS Library for Next.js App Router

[encodeincode]

Hello, HN! I'm excited to introduce StayedCSS, a static CSS library built specifically for the Next.js App Router.

StayedCSS fully supports server and client components using a syntax inspired by pure CSS. I created this library to meet the need for efficient styling in both SSR and 'use client' environments. With features like media queries, pseudo-elements, pseudo-classes, combinators, and smooth dark mode transitions, StayedCSS is designed to elevate your Next.js projects.

Currently in beta, StayedCSS is being actively optimized and improved. Your feedback is incredibly valuable, so feel free to share your thoughts.

Thank you!
