Semantic UI is a comprehensive front-end development framework that utilizes human-friendly HTML to create responsive, mobile-friendly websites. The framework provides a wide range of UI components, including buttons, menus, forms, and modals, along with many pre-built themes that can be customized to suit your project. Semantic UI is also built with accessibility in mind, adhering to WAI-ARIA standards to ensure compatibility with assistive technologies like screen readers.

Styled-JSX is a library that allows you to write scoped CSS for your React components. It provides a way to style your components using traditional CSS syntax, while ensuring that the styles only apply to that component and not its children or parent. This is achieved through the use of CSS modules and a custom babel plugin which transforms the styles to a unique class name with randomly generated hashes.

Alternatives: styled-components, emotion, aphrodite

Semantic UI is a widely popular CSS framework in the JavaScript community. It has a large user base and active community support. Styled-JSX, on the other hand, is a lesser-known library that enables you to write scoped, component-level CSS using a CSS-in-JS approach.

CSS Framework vs CSS-in-JS

Semantic UI is a comprehensive CSS framework that provides pre-defined styling and components. It offers a wide range of ready-to-use UI elements and a consistent design system. Styled-JSX, on the other hand, is a CSS-in-JS solution that allows you to write CSS directly within your JavaScript or JSX code. This gives you more flexibility and control over styling but requires you to write CSS code.

Integration with React

Both Semantic UI and Styled-JSX can be used with React. Semantic UI provides a set of pre-built React components that are designed to work seamlessly with the framework. Styled-JSX, on the other hand, is a more general-purpose CSS-in-JS library that can be used with any JavaScript framework, including React.

Ease of use

Semantic UI offers an extensive set of pre-styled components that can be easily used in your React application. It provides a declarative syntax for building UI elements, making it beginner-friendly. Styled-JSX requires you to write CSS within your JavaScript code, which might have a steeper learning curve, especially for developers who are not familiar with CSS-in-JS solutions.

Styling Approach

Semantic UI follows a more traditional approach to styling, where you apply predefined CSS classes to your UI elements. Styled-JSX allows you to write inline, scoped CSS using JavaScript template literals. This gives you more fine-grained control over styling and eliminates class name clashes.


Semantic UI provides a theming system that allows you to customize the overall look and feel of your application. It provides a set of variables and tools to customize the default styles. Styled-JSX, on the other hand, allows you to customize styles at the component level by using dynamic values and CSS logic directly in your JavaScript code.
