@emotion/css is a popular CSS-in-JS library in the React ecosystem. It has gained significant popularity due to its powerful styling capabilities and excellent developer experience. Bulma, on the other hand, is a popular CSS framework based on Flexbox. It provides a wide range of pre-designed, responsive components. Both packages are widely used, but @emotion/css is specifically popular among React developers.

Styling Approach

@emotion/css is a CSS-in-JS library that allows you to write styles directly in your JavaScript or TypeScript files. It offers various styling features such as theming, composition, and dynamic styles. Bulma, on the other hand, is a CSS framework that provides pre-built CSS classes for styling HTML elements. It follows a more traditional approach where you write HTML with class names instead of inline CSS or JS styles.


@emotion/css provides a high level of customization. You can create your own custom CSS-in-JS styles, define global styles, and easily modify styles based on props or state. Bulma also allows customization, providing a Sass-based workflow to customize variables and override default styles. However, @emotion/css offers more flexibility in terms of creating custom styling solutions.

Component Ecosystem

Bulma provides a comprehensive set of reusable components such as navigation bars, buttons, forms, and grids. These components are designed to be responsive, mobile-friendly, and highly customizable. @emotion/css, being a CSS-in-JS library, does not offer pre-built components out of the box. However, it provides a solid foundation for building custom React components with expressive and scoped styles.


@emotion/css seamlessly integrates with React and other JavaScript frameworks. It provides hooks and utilities specifically designed for React development, making it easy to manage styles within component lifecycles. Bulma can be used with any web framework, including React. It requires setting up the CSS framework, importing necessary stylesheets, and applying Bulma classes to HTML elements.

Learning Curve

Both @emotion/css and Bulma have a relatively low learning curve. However, @emotion/css requires some understanding of JavaScript or TypeScript concepts as you write styles directly in your code. Bulma, on the other hand, is more straightforward to use, as it relies on class names defined in CSS stylesheets. Both libraries have good documentation and active communities that can help with any learning hurdles.
