A utility-first CSS framework that offers a variety of classes such as flex, pt-4, text-center, and rotate-90 allows developers to create any design directly within their markup. By utilizing utility classes, you can adhere to a systematic approach without cluttering your stylesheets with random values. This method facilitates consistent choices regarding colors, spacing, typography, shadows, and all other elements that contribute to a well-structured design system. The low-level nature of Tailwind means it doesn't push you to replicate the same design across different sites. Even when using identical color palettes and sizing scales, you can easily craft the same component to achieve a distinct appearance in a new project. Moreover, Tailwind efficiently purges all unused CSS during production builds, ensuring that the final CSS bundle remains as compact as possible. As a result, many Tailwind projects deliver less than 10kB of CSS to users, exemplifying the framework's efficiency and effectiveness in web design. This lightweight approach not only enhances site performance but also improves loading times for end-users.
