Tailwind CSS is a utility-first CSS framework that lets you build custom designs directly in your markup. V4 added a Rust-based engine, CSS-first configuration, and automatic content detection. The default choice for modern web development.
Reviewer scorecard
“Still the most used JS testing framework. Massive ecosystem of matchers, plugins, and documentation.”
“V4 is the fastest CSS framework to build with. No context switching between files, instant builds, and the design system constraints prevent spaghetti CSS. Industry standard for a reason.”
“Vitest does everything Jest does faster with better ESM support. New projects should start with Vitest.”
“The 'ugly HTML' argument is dead. With component extraction and proper tooling, Tailwind codebases are more maintainable than traditional CSS. The ecosystem (shadcn, daisyUI) seals it.”
“Jest defined modern JS testing but Vitest is the future. The migration is happening steadily.”
“AI tools generate Tailwind better than any other CSS approach. When v0 or Claude writes UI code, it's Tailwind. That alone makes it the right choice for AI-assisted development.”
