Bulma is a free, open-source, and lightweight CSS framework based on the CSS Flexbox layout, designed to help developers efficiently style HTML code for responsive web pages without writing JavaScript. It emphasizes simplicity and flexibility, offering features like modularity, a massive library of interactive elements, and a straightforward syntax with class-based styling. Bulma is compatible with modern browsers but has partial support for Internet Explorer. It allows developers to import only the necessary components, thus optimizing website performance through faster load times and reduced code. Bulma's design is modern and minimalist, providing more control over appearance, while its easy-to-learn syntax includes self-explanatory class names and direct modifiers. Compared to Bootstrap, Bulma offers more flexibility in customization but has a smaller support community. The framework is ideal for developers who prefer focusing on styling without complex scripting, and its modular nature helps maintain efficient, maintainable code.
