In this React tutorial, you'll learn how to create a Theme Provider from scratch using the React Context API. Instead of writing duplicate CSS for every component, we'll build a centralized theme system that stores colors, fonts, spacing, border radius, and reusable styles in JavaScript.
This approach makes your React project clean, scalable, and easy to maintain. It is also a great foundation for implementing Light Mode and Dark Mode in the future.
