Tailwind CSS is a utility-first CSS framework that lets you build user interfaces by composing small, single-purpose CSS classes directly in your HTML. Instead of writing custom CSS or using pre-made components, you apply utility classes like `flex`, `text-lg`, and `bg-blue-500` to quickly style elements and create responsive layouts. Developers choose Tailwind for its speed and flexibility—it eliminates context-switching between HTML and CSS files, reduces the need to name classes, and scales well for projects of any size.
