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-components is a popular CSS-in-JS library for building user interfaces in modern web applications. It allows developers to define styles for their React components using JavaScript and provides simple, intuitive APIs for managing them.

Both Semantic UI and Styled Components are popular npm packages within the frontend development community. However, Styled Components has gained significant popularity in recent years and is widely used in modern React projects. It has a large and active community support.

Styling Approach

Semantic UI is a CSS framework that provides pre-styled components, whereas Styled Components is a CSS-in-JS library that allows you to write CSS code directly in your JavaScript code. Semantic UI provides a set of ready-to-use components with defined styles, while Styled Components allows you to create custom and reusable components with dynamic styles.


Styled Components offers more flexibility in terms of styling. You can leverage JavaScript features like conditional styling, dynamic theming, and props-based styles. Semantic UI, on the other hand, provides a more opinionated set of styles and components, which may limit flexibility for certain use cases.

Development Experience

Both packages have a good developer experience. Semantic UI provides a wide range of pre-built components that can be easily customized. Styled Components, on the other hand, offers a seamless integration with React, allowing you to write styles co-located with your components. The strong combination of CSS and JavaScript makes Styled Components more maintainable and scalable in larger projects.


Semantic UI is primarily designed for use with jQuery and traditional web development workflows. It requires additional configuration and may not be as compatible with modern front-end frameworks like React. Styled Components, on the other hand, is specifically built for React and integrates smoothly with the React component-based architecture. It is widely used in React projects.


In terms of performance, Semantic UI has a larger footprint due to its predefined set of styles and components. Styled Components, being a CSS-in-JS library, allows you to optimize CSS rendering and reduce unnecessary re-renders. However, the performance difference may depend on the specific use case and the implementation of the components.
