Tailwind CSS
also Tailwind
A utility-first CSS framework where you style elements by composing small classes directly in your markup instead of writing separate CSS files.
Analogy
Like a paint roller instead of a fine brush — much faster to cover ground.
Why it matters
It's the fastest way to style modern Next.js pages, so it speeds up building branded UIs (this hub uses it).
In practice
class="flex bg-black text-white p-4 rounded" styles an element with no CSS file.
