What is Nimble.css?

Nimble.css is a lightweight CSS framework that automatically styles standard HTML elements without requiring any class names. At just 4.1 KB brotli, it provides elegant default styling for all semantic HTML tags, dark mode support, and cascade layers for compatibility with custom styles. The library uses CSS custom properties for easy runtime customization without build steps.

Designed for developers who want clean, semantic HTML with professional styling out of the box. It combines aesthetic inspiration from Pico CSS with design tokens from Open Props, offering a minimal alternative to larger frameworks. The maker reports it was built with assistance from Claude.
