Tailwind CSS is a utility-first CSS framework that allows developers to build modern websites directly within their HTML markup. It provides a comprehensive set of pre-defined classes like `flex`, `pt-4`, `text-center`, and `rotate-90` that can be composed to create any design without writing custom CSS.
The framework is designed for the modern web, leveraging the latest CSS features to enhance the developer experience. Key features include responsive design utilities, filters, dark mode support, easy theme customization via CSS variables, P3 color support for vibrant palettes, and simplified CSS grid layouts. It also offers intuitive transitions and animations, uses CSS layers to manage specificity, supports logical properties for multi-language text directions, and includes container queries for adaptive components.
Tailwind CSS is ideal for developers who want to streamline their styling workflow, reduce context switching, and build highly customizable and performant user interfaces efficiently. It aims to make front-end development more enjoyable by providing powerful tools that integrate seamlessly into the HTML structure.
