React Styling Patterns
In traditional web development, HTML and CSS are completely separate. In React, components blend logic and UI, which gave rise to entirely new ways of managing styles.
Inline Styles
Instead of a string, the style attribute in React expects a JavaScript object. CSS properties with hyphens become camelCased (e.g., background-color becomes backgroundColor). While easy for dynamic values, they lack support for media queries and pseudo-selectors.
CSS Modules
A CSS Module is simply a CSS file where all class names are scoped locally by default. When you import it, React generates a unique hash for the class, solving the global namespace problem of traditional CSS files.
CSS-in-JS & Utility Libraries
Libraries like styled-components let you write CSS directly inside your JS using template literals, binding styles strictly to a component. Alternatively, utility-first approaches like Tailwind CSS provide thousands of predefined classes, letting you style elements directly in the JSX className without writing custom CSS rules.
