What is Tailwind CSS?
A utility-first CSS framework where you style elements by composing small, single-purpose classes directly in your HTML.
Instead of writing custom CSS, you apply pre-built utility classes: text-lg for font size, p-4 for padding, bg-white for background. Tailwind eliminates the naming problem (no more .card-header-wrapper), co-locates styles with markup, and works exceptionally well with AI code generation because the class names are systematic and predictable.
