How To Style React Components With CSS Modules
Styling React components with CSS Modules is a technique that allows developers to write CSS that is scoped locally to the component rather than globally. This is achieved by creating a CSS file with the extension `.module.css`, where class names are automatically transformed into unique identifiers during the build process. When importing these styles into a React component, developers reference the class names as properties of an imported object, ensuring that styles are applied specifically to that component. This approach prevents naming collisions and promotes modularity, making it easier to manage and maintain styles as the application grows. With CSS Modules, developers can leverage the full power of CSS while maintaining cleaner and more organized code.

react and graphql Basics
React is a popular JavaScript library used for building user interfaces, particularly for single-page applications, by creating reusable UI components that efficiently update when data changes. It uses a virtual DOM to optimize rendering, making applications faster and more responsive. GraphQL, on the other hand, is a query language for APIs that allows clients to request only the specific data they need, rather than retrieving fixed data structures. This flexibility reduces the amount of data transferred over the network and simplifies data management in applications. When used together, React and GraphQL provide a robust framework for developing interactive and data-driven web applications.
