Build your own type-safe version of Tailwind CSS with Sprinkles

Vanilla-extract, a CSS-in-JS library created by Mark Dalgleish, is praised for its ability to leverage TypeScript for CSS, offering a compelling alternative to popular tools like Tailwind CSS. The library's standout feature, the Sprinkles API, allows users to create a fully customized, utility-first CSS framework from scratch, offering benefits such as type safety, customization, and local scope. This tutorial illustrates how to set up a Next.js app using vanilla-extract and Sprinkles to develop a custom design system named Sprinkles Tailwind, capable of replicating Tailwind CSS's product card demo while addressing pseudo-classes, responsive design, and dark mode themes. Sprinkles provides a type-safe environment that simplifies the CSS development process compared to Tailwind, offering immediate feedback on errors and allowing for flexible, component-scoped styles. The guide concludes with implementing responsive design and dark theme capabilities, demonstrating Sprinkles' versatility in creating modern, theme-aware web components.
