Using CSS variables in React Native

In the context of React Native applications, styling plays a crucial role in creating visually appealing user interfaces, similar to web development. Developers have multiple options for styling, including CSS, SCSS stylesheets, CSS Modules, styled-components, and the StyleSheet API, which is recommended for abstracting styles and improving code readability. styled-components is particularly popular for enabling component-level styles with CSS-in-JS techniques. The use of CSS variables, or custom properties, is highlighted as a modern approach to enhance styling by allowing reusability and maintainability, enabling consistent themes across applications, and simplifying updates to style properties. The document demonstrates how CSS variables can be implemented in React Native for creating global styles and dynamic styling changes, while also cautioning against overuse due to potential performance impacts. Additionally, it suggests best practices for naming and organizing CSS variables to separate application logic from design elements, and provides resources for further exploration of CSS variables in various contexts.
