Bulma

Bulma is a design-agnostic CSS framework that provides a collection of pre-styled interface components and layout primitives. It is built to be independent of specific JavaScript frameworks or build tools, allowing developers to construct responsive web interfaces by applying standardized classes directly to semantic HTML markup.

The framework distinguishes itself through a utility-first approach that combines modular component styling with a flexible grid system. It leverages native CSS variables to manage design tokens, enabling real-time visual customization, automatic dark mode adaptation, and theme overrides without requiring code recompilation. This architecture ensures a consistent visual identity across projects while maintaining a lightweight footprint.

The project covers a comprehensive capability surface, including responsive layout containers, navigation systems, and interactive form controls. It provides granular helper classes for spacing, typography, and alignment, alongside preprocessor-driven tools that facilitate style reuse and modular component organization. These features collectively support rapid frontend prototyping and the implementation of cohesive design systems across modern web browsers.
