Mastering Tailwind CSS v4 in Next.js Projects

Tailwind CSS v4 introduces CSS-first configuration. Instead of editing JavaScript config files, custom themes are defined directly in CSS using simple directives.

What is New in Tailwind v4? * **Rust-based Compiler:** Performance is up to 10x faster, ensuring fluid re-compiles during hot-module-replacement. * **Implicit @theme Rules:** Customize or extend color palettes, animations, and typography using CSS variables inside your stylesheet. * **Native Cascading Styles:** Cleaner integration with global presets, making overrides straightforward.
