Styleds

Styleds refers to a set of CSS-in-JS libraries commonly used in modern web development. These libraries allow developers to write CSS directly within their JavaScript or TypeScript files, rather than in separate `.css` files. The primary goal of Styleds is to enable component-scoped styling, meaning that styles are tightly coupled to the components they are intended for, preventing style conflicts and improving maintainability.

One of the most popular libraries within the Styleds family is Styled Components. It leverages tagged template literals in JavaScript to create React components with attached styles. This approach provides dynamic styling capabilities, allowing styles to be easily manipulated based on component props. Other notable libraries in this category include Emotion, which offers similar functionality with a slightly different API, and JSS, a library for generating CSS classes and styles from JavaScript objects.

The benefits of using Styleds include improved developer experience through co-location of styles and logic, enhanced code organization, and easier theme management. By encapsulating styles within components, developers can manage them more effectively, especially in large and complex applications. This approach also facilitates the creation of reusable and composable UI elements. Styleds libraries often include features like automatic vendor prefixing, server-side rendering support, and performance optimizations.
