Tailwind CSS has gone from controversial utility-first experiment to the default CSS framework for modern web development. In 2026, it ships with virtually every new Next.js, Astro, and SvelteKit project. The ecosystem around it has grown to match: there are now dedicated component libraries, AI-powered generators, VS Code extensions, and browser tools that make building Tailwind UIs significantly faster.
